Plantar fasciitis is the most common cause of heel pain, and for most people it improves with conservative care. But a stubborn minority of cases drag on for months despite doing everything right. That’s where regenerative options like PRP enter the conversation. Here’s an honest look at what PRP is, how it might help plantar fasciitis, and what to expect.

What is plantar fasciitis?

The plantar fascia is a thick band of tissue running along the bottom of your foot from the heel to the toes. When it’s overloaded or irritated, it becomes painful — classically a sharp pain under the heel with your first steps in the morning. Most cases stem from a mix of tight calves, foot mechanics, activity load, and footwear. You can read more on our plantar fasciitis page.

What is PRP and how could it help?

PRP is made from a small sample of your own blood, spun in a centrifuge to concentrate the platelets and the growth factors they carry. That concentrate is injected into the injured area of the plantar fascia. The idea is to support the body’s natural repair process in tissue that has been slow to heal on its own.

When is PRP considered for plantar fasciitis?

PRP is generally discussed only after conservative care has had a fair trial. That usually means several weeks to months of stretching, orthotics or supportive footwear, activity modification, and sometimes physical therapy. If pain persists despite all that, PRP may be one of the next options to weigh — alongside other treatments — depending on your specific situation.

What does the treatment involve?

The process is straightforward: blood is drawn from your arm, spun to prepare the PRP, and injected into the heel area, typically with a local anesthetic for comfort. It’s an in-office procedure. Afterward, some soreness for a few days is normal, and you’ll usually be advised to limit high-impact activity for a short time.

What results can you realistically expect?

This is where honesty matters. PRP does not work for everyone, and studies on it show mixed results. Some patients experience meaningful improvement; others don’t. It is best understood as one option within a broader plan — not a miracle cure and not a substitute for addressing the mechanics that caused the problem in the first place. Your podiatrist should give you a realistic picture based on your exam.

PRP vs. cortisone for plantar fasciitis

Cortisone injections can reduce inflammation and provide faster short-term relief, but repeated cortisone in the heel carries risks to the fascia and fat pad over time. PRP aims to support healing rather than simply calm inflammation. Neither is right for every patient — the choice depends on your diagnosis and history.
