I get a lot of exercise for a 49 yr old. (since my 5 bypasses). I play recreational basketball 4x a week. While playing, I developed disabling pain from my lower calf to the top of my heal. The injury felt like a sprain that got progressively worse over a 20 minute period. I took a week off and the pain eased, and retreated to the area where the achilles anchors to the top of the heel. But, it returns when I resume activities. The pain can be rather sharp, and I wonder if I have a spur that is irritating the tendon.
