How effective is PRP injection for plantar fasciitis?

Plantar fasciitis involves irritation and degenerative change in the plantar fascia, the band supporting the sole of the foot. PRP is made from your blood and injected near the painful fascia. The intended effect is to support local tissue recovery and reduce symptoms over time, rather than provide an instant correction. Heel pain can also come from nerve irritation, a stress injury, fat-pad problems or another condition, so the diagnosis matters. A heel spur on imaging does not by itself explain every symptom. Read the [Plantar Fasciitis](/conditions/plantar-fasciitis/) overview for more context.

Review walking demands, footwear, calf flexibility, foot strength and recent changes in activity. A physiotherapist may prescribe plantar fascia and calf stretches, strengthening for the foot and lower limb, and a gradual increase in standing, walking or running. PRP aftercare can include a temporary reduction in impact; follow the individual instructions from the clinician who performs it. Track first-step pain, walking tolerance and next-day symptoms rather than judging the result immediately. The [PRP Injection](/treatments/non-surgical-orthopedics/prp-injection/) guide explains the procedure more broadly.

Arrange prompt assessment for sudden severe heel pain after an injury, inability to bear weight, spreading redness, fever, marked swelling, numbness or a changing foot colour. After an injection, worsening warmth, drainage, fever or escalating pain should be reported to the treating service.

Is the plantar fascia the confirmed pain source? What improvement should we track? How long will impact activity be modified? Which exercises and footwear changes should accompany PRP?
