Hi. I was recently trying to exercise and get in shape by running. I was up to running 6 miles and suddenly while running developed pain in the heel, along the side. It is painful to walk, but not to stand. There is pain when pushing in on both sides of the achilles tendon, but directly on the achilles, a little below the ankle bones. There is also swelling and some discoloration. I would appreciate any advice. I have been icing and taking ibuprofen.
