What it actually feels like
The first step out of bed is the one people remember. A sharp, focused pain under the inside of the heel, bad enough to make you walk on the outside of the foot for the first minute. After a few dozen steps it fades to something manageable, and by mid-morning it may be nearly gone. Then you sit through a meeting or a flight, stand up, and it is back exactly as it was.
That pattern — severe with the first steps after rest, easing with movement, returning after sitting — is close to diagnostic on its own. Later in the day the character changes: a duller, broader ache across the heel that worsens with time on your feet rather than improving.
Most people can put one fingertip on the spot. It is on the inside of the sole of the heel, right where the fascia attaches to the heel bone, and pressing it reproduces the pain precisely. That specificity is useful, because heel pain that cannot be localised to that point is often not plantar fasciitis.
Why "fasciitis" is the wrong word
The condition is named for inflammation, and inflammation is largely not what is there. Tissue examined from long-standing cases shows collagen degeneration, disorganised fibres, and an ingrowth of small vessels and nerves — the same degenerative picture found in chronic tendon problems elsewhere in the body. Plantar fasciopathy is the more accurate term, and it has a practical consequence: treatments aimed at suppressing inflammation are aimed at something that is not the main problem.
This is also why the condition is stubborn. Degenerative tissue does not resolve on the timescale that inflammation does. It has to remodel, and remodelling is measured in months and driven by load rather than by rest.
What the plantar fascia actually does
The plantar fascia is a thick band running from the heel bone forward to the base of the toes. It is not a muscle and it does not contract. It works as a tension element: as you push off, the toes extend, the fascia winds tight around the ball of the foot and pulls the heel and forefoot toward each other, converting a flexible foot into a rigid lever. Every step you take depends on it.
Two things follow. First, this tissue is loaded thousands of times a day and cannot be rested in any meaningful sense short of crutches. Second, the calf matters enormously. A tight gastrocnemius limits ankle dorsiflexion, which forces the midfoot and the fascia to absorb motion the ankle should have provided. Calf tightness is one of the most consistent findings in people with plantar heel pain, and one of the most consistently under-treated.
How the foot is examined here
The examination starts with the fingertip test — exactly where, and does pressure there reproduce your pain. Then the windlass test, extending the great toe to tighten the fascia and see whether that provokes symptoms. Then ankle dorsiflexion measured with the knee straight and again with it bent, which separates a tight gastrocnemius from a tight soleus and changes the stretching programme. Then a look at the arch under load, the wear pattern on your shoes, and the fat pad, because heel pad atrophy causes heel pain that looks similar and is treated entirely differently.
Nerve findings are checked deliberately: burning, tingling, night pain or symptoms radiating into the foot suggest entrapment of the first branch of the lateral plantar nerve, which sits close by and accounts for a meaningful share of heel pain that fails to respond to fascia-directed treatment.
Then ultrasound, in the same visit. It measures fascial thickness directly — a normal fascia is thin, and a thickened one is objective evidence rather than an impression — and it shows the degenerative change, any calcification, and whether there is a partial tear. It also gives a number that can be repeated at follow-up, which matters when progress is slow enough that memory becomes unreliable.
X-rays are ordered when a calcaneal stress fracture is a possibility. They are not ordered to look for a heel spur, because finding one would not change anything.
What the evidence supports, and what it does not
The corticosteroid problem is different here, and worse
With tennis elbow, the argument against corticosteroid is that twelve-month outcomes are worse. In the heel there is that concern plus two specific structural risks: rupture of the plantar fascia and atrophy of the heel fat pad.
A ruptured plantar fascia is not a minor complication. It can flatten the arch, shift load across the midfoot, and produce a problem more durable and harder to treat than the one that prompted the injection. Fat pad atrophy is worse in one respect: the heel pad is specialised shock-absorbing tissue that does not regenerate, and once it is thinned, every step lands on a heel with less protection than it was built with. Both risks rise with repeated injections.
Patients are routinely offered a heel injection without either risk being mentioned. That is the single most common thing we end up correcting in this condition.
Where PRP sits
Randomized trials comparing platelet-rich plasma with corticosteroid for plantar fasciopathy have generally found the two comparable at four to six weeks, with PRP ahead at three, six and twelve months. The trajectory mirrors what is seen in tendinopathy elsewhere, which is what you would expect given the tissue is doing the same thing.
The honest caveats are the same as everywhere in this field. Trial quality varies, preparation protocols vary enormously, and a low-dose preparation injected without imaging is not the same intervention as a high-dose preparation placed under ultrasound into the specific degenerative segment. Comparisons against saline are less clear-cut than comparisons against steroid, and needling the fascia may itself contribute.
What can be said fairly: PRP has a better long-term profile than corticosteroid in this condition, and it does not carry a rupture or fat pad risk.
What has the best evidence of all
Plantar fascia-specific stretching and calf stretching, done consistently, outperform most injections at twelve months. This is unglamorous and it is true. Any discussion of injections for heel pain that does not start here is skipping the intervention with the strongest supporting data.
The options, all of them
Stretching and loading
Two distinct things, both necessary. Plantar fascia-specific stretching — pulling the toes back to tension the fascia before the first steps of the day — targets the tissue directly and is done before weight-bearing, which is the whole point. Calf stretching addresses the dorsiflexion restriction that keeps reloading it. Progressive strengthening of the calf and intrinsic foot muscles has increasingly good support and is the part most programmes leave out.
Footwear, orthoses and night splints
A supportive shoe with a modest heel-to-toe drop reduces fascial tension. Over-the-counter inserts perform about as well as custom orthoses for most people, which is worth knowing before spending several hundred dollars. Night splints hold the ankle in a neutral position so the fascia does not shorten overnight; they work for some people and are tolerated by fewer, but they directly target the first-step mechanism.
Corticosteroid injection
We do not use corticosteroid injections for plantar fasciitis. One of the reasons is the one described above: the risk of plantar fascia rupture and of thinning the heel fat pad. A ruptured fascia can be a worse and more durable problem than the one being treated, and fat pad atrophy does not reverse. Given that a treatment exists which carries neither risk and does better at six and twelve months, we do not see a reason to accept them.
Orthobiologic injection
Platelet-rich plasma prepared from your own blood on the day, injected under ultrasound guidance into the degenerative portion of the fascia, with a partial tear targeted directly if one is present. Expect the heel to be more sore for several days. Anti-inflammatories are avoided around the procedure. It is combined with the stretching and loading programme rather than substituted for it.
Our ultrasound-guided medial approach to injecting PRP for plantar fasciitis is an approach we have taught to many clinicians, and it is a safe and effective alternative to the steroid shot.
Why we do not inject through the sole of the foot
The obvious way to reach the plantar fascia is straight up through the bottom of the heel. It is also the way that hurts most. The sole is densely innervated, the skin there is thick and tightly bound, and injecting through it is the reason heel injections have the reputation they have.
We approach the fascia from the medial side of the heel instead, under ultrasound guidance. The needle travels through softer, less sensitive tissue, and the ultrasound shows the fascia and the needle tip throughout, so the injection is placed in the degenerative segment rather than approximately near it. It is substantially more comfortable, and it is more accurate — those two things are not a trade-off here.
This is the technique we have taught to other clinicians. If you have had a heel injection before and are dreading another one, this is the part of the page worth asking about.
Class IV MLS laser therapy
Offered as an adjunct alongside loading or after an injection. Comfortable, no downtime, and a smaller evidence base than stretching or PRP. It is presented on those terms.
Extracorporeal shockwave therapy
Reasonable evidence in chronic cases that have failed conservative care, and a legitimate option to discuss for someone who wants to avoid an injection.
Surgery
Rarely required. Partial plantar fascia release is reserved for a small group with genuinely refractory symptoms after a year or more of properly executed conservative treatment, and it carries its own risk of destabilising the arch. Gastrocnemius recession is an alternative in patients whose primary driver is a fixed calf contracture. Most people with heel pain never need either.
How the choice actually gets made
Duration and what has already been tried drive most of it.
Under three months, nothing tried — a properly structured stretching and loading programme, appropriate footwear, and time. This is the intervention with the best long-term evidence and starting elsewhere gives it away.
Three to six months, programme genuinely followed, still limited — the point at which orthobiologic injection becomes a sensible conversation, with the loading programme continuing rather than stopping.
Any previous corticosteroid injections — the fascia is examined specifically for a tear and the fat pad for thinning before anything else is planned.
Burning, tingling, or night pain — the working diagnosis is reconsidered before any injection, because nerve entrapment will not respond to treatment aimed at the fascia and injecting it wastes months.
Why a surgeon is the one saying this
Dr. Buford is a board-certified orthopedic surgeon. When the recommendation is that you do not need a procedure, it is coming from the person who would otherwise perform it. And when heel pain genuinely does need surgical attention — which is uncommon but not never — it is recognised rather than treated indefinitely with injections by a clinic that has no other option to offer.
What recovery involves
After an orthobiologic injection, expect three to five days of increased soreness. A walking boot is occasionally used for a short period. Anti-inflammatory medication is avoided for a defined window. Stretching resumes early; loading progresses deliberately.
Improvement is measured in months. Most people notice change between six and twelve weeks, and it often continues beyond that. The morning first-step pain is usually the last symptom to go, and its disappearance is the most reliable sign that the tissue has actually remodelled rather than simply quietened down.
The relapse most people have is the same one: symptoms improve, the stretching stops, and three months later it is back. The programme is not finished when the pain goes.
Common questions
Why does it hurt most on the first step in the morning?
Overnight the foot rests in a slightly pointed position and the plantar fascia shortens and begins to knit together at the site of the degeneration. The first weight-bearing step of the day pulls that tissue apart again. Walking for a few minutes stretches it out and the pain eases, which is why people convince themselves it is improving right up until the following morning. That specific pattern is close to diagnostic.
Is the heel spur causing my pain?
Almost certainly not. Heel spurs are common in people with no heel pain at all and absent in many people who have it, and the spur sits within a different structure than the one that hurts. It is a consequence of long-standing traction rather than a cause of pain. Surgical removal of a spur for plantar heel pain is not something we recommend, and an X-ray showing one does not change the treatment plan.
Should I get a cortisone shot in my heel?
We do not use corticosteroid injections for plantar fasciitis. A steroid shot into the plantar fascia does give good short-term relief, but it carries two specific risks that patients are frequently not told about: rupture of the plantar fascia, and atrophy of the heel fat pad. A ruptured fascia can produce a worse and more durable problem than the one being treated, fat pad atrophy is not reversible, and both risks rise with repeated injections. Since platelet-rich plasma carries neither risk and performs better at six and twelve months, we do not see a reason to accept them.
Does PRP work for plantar fasciitis?
The evidence is reasonably encouraging. Randomized trials comparing platelet-rich plasma with corticosteroid have generally found the two similar in the first month and PRP better at three, six and twelve months, which mirrors the pattern seen in tendon problems elsewhere. PRP also avoids the rupture and fat pad risks that come with steroid. It is not a certainty, it is not instant, and it works best alongside a loading and stretching programme rather than instead of one.
Does the injection hurt? I have heard heel injections are terrible.
That reputation comes from injecting through the sole of the foot, which is densely innervated and genuinely unpleasant. We do not use that approach. We inject from the medial side of the heel under ultrasound guidance, through softer and far less sensitive tissue, watching the needle tip and the fascia throughout. It is substantially more comfortable and it is also more accurate, because the injection goes into the degenerative segment rather than approximately near it. This is the technique we have taught to many other clinicians.
How long does plantar fasciitis take to resolve?
Roughly eight or nine in ten cases settle within about a year with consistent conservative care. That figure cuts both ways. It means most people will get better, and it means any treatment given late in the course will appear to work regardless of whether it did anything. The purpose of treating is to shorten the timeline, to identify the minority who will not resolve on their own, and to avoid interventions that make things worse.
Do I need an MRI?
Usually not. Plantar fasciitis is diagnosed clinically and confirmed with ultrasound in the office, which measures fascial thickness, shows the degenerative change directly, and identifies a partial tear if one is present. MRI becomes worthwhile when the presentation is atypical: suspicion of a calcaneal stress fracture, nerve entrapment, or heel pain that has not behaved the way plantar fasciitis behaves.
Who performs the injection?
Dr. Buford performs every injection himself, under direct ultrasound guidance. No physician assistant, nurse practitioner, or technician performs orthobiologic injections at Texas Orthobiologics. Call 877-777-8883 to arrange an evaluation.
