For the last two weeks now. I have started having a pain in the back of the foot and heel area, only after playing Sand Volleyball. I play on Sunday nights and after we are done. I have a pain. Well, the next morning it is VERY painful, and lasts for a couple of days. It is uncomfortable to walk on for those few days. The pain is a burning, dullish pain for the most part. But, is does go away until I play Sand Volleyball again…..I also play softball on the weekend. However it has never bothered me after those games.
