How long does PRP injection take to work for plantar fasciitis?

PRP is placed near the painful plantar fascia to support a local healing response. It does not numb the heel immediately, and the area can feel more tender for a short period afterward. Progress may first show as less pain with the first steps in the morning, more comfortable standing, or better tolerance of a normal walk.

Symptoms can fluctuate when barefoot walking, long standing, or sudden increases in exercise overload the fascia. A flare does not automatically show that treatment has failed, but repeated flares deserve review so the rehabilitation plan can be adjusted.

Use the footwear, activity limits, and exercises recommended for you. Avoid repeatedly checking the heel with long walks or impact exercise while it is sore. A physiotherapist may introduce calf and foot strengthening, then increase walking or sport demands in measured stages.

Note morning pain, walking tolerance, and the activities that bring symptoms on. Bring this pattern to your appointment. Background information is available in [Plantar Fasciitis](/conditions/plantar-fasciitis/) and [PRP Injection](/treatments/non-surgical-orthopedics/prp-injection/).

Tell the clinic if heel pain is worsening rather than settling, the injection area becomes hot or increasingly red, or you feel unwell or develop fever. Seek urgent care for sudden inability to walk, rapidly increasing swelling, new calf swelling, or breathing difficulty.

Ask when to restart stretching or strengthening, which footwear is appropriate, how much walking is reasonable, and how you will distinguish expected soreness from a complication. Ask what review is planned if your morning steps remain painful.
