When Is PRP Injection Recommended for Plantar Fasciitis?

Plantar fasciitis involves the thick band of tissue under the foot and commonly causes pain near the heel, especially with the first steps after rest. Heel pain can also come from a nerve, stress injury, tendon problem or another condition. A clinician considers the pain pattern, foot movement, calf flexibility, footwear, activity and examination findings before recommending an injection. PRP uses a prepared portion of your own blood and is placed near the painful plantar fascia; it may support symptom improvement but does not make recovery immediate.

Record when the pain occurs, whether walking barefoot or standing worsens it, and which measures have helped. A care plan may include calf and foot exercises, gradual activity changes, supportive footwear and advice about returning to impact. If PRP is suggested, ask how the fascia was diagnosed, what aftercare involves and how rehabilitation will continue. More detail is available in [Plantar Fasciitis](/conditions/plantar-fasciitis/) and [PRP Injection](/treatments/non-surgical-orthopedics/prp-injection/).

Seek prompt care if heel pain follows a significant injury, you cannot bear weight, the foot is visibly swollen or deformed, or you develop numbness or weakness. Fever, spreading redness or a wound also requires urgent review. Those findings are not a reason to proceed directly to an elective PRP injection; they need a timely search for another cause.

What is causing my heel pain? Have we addressed calf tightness and foot strength? Which activities should I pause or modify? Where would PRP be injected, and what recovery plan follows? What other options are appropriate if symptoms continue?
