go to an orthopedic doctor or if your concern is only the ankle then see a podiatrist. Phill
Hello!
Check for any local infection due to cellulitis if the area is swollen, red, painful and hot.
If not you would need to follow up with a local physician and check for any issues like local injury, fatigue and rule out conditions like diabetes and measure your vitals.
If the symptoms do not subside with rest and NSAIDs and if all your vitals are normal then you would need an orthopedician for a proper diagnosis.
Take care!
