Hello! I am 53, female, with left posterior heel pain. I am overweight (200 lbs.) and I walk and.or hike about 6-7 hours per week (usually a 3-5 mile walk or hike, sometimes shorter). I also walk about half a mile each morning to the bus stop. I wear hiking boots or Mephisto walking shoes when I go on long walks or hikes, Anyway, I have three weeks of continuing pain in the left posterior heel. It is very annoying. Last night, this was accompanied by a weird itching sensation just underneath my heel (like a tingling itch underneath the skin). There is nothing visibly wrong -- no swelling, bumps, bruising. etc. It hurts more if I flex my foot. What is it...? I hope it s not from walking because that is the only exercise I get and I love it!
