Sharp pain in my heel when i flex my foot upwards.what could it bw and what can o do?

Heel Pain: We worry about plantar fasciitis, but you might need to have this evaluated by your primary care doctor who might refer you to a physical therapist to teach stretching exercises. Try a heating pad and some gentle anti-inflammatory meds until you can see your doctor.

Achilles?: This may represent a problem with the achilles tendon. I recommend seeing an orthopaedic foot and ankle surgeon. One in your area can be found at www.Aofas.Org.
