recurring injury

I have a bad foot... literally. Over the past 10 years of skateboarding i have counted up numerous injuries to my left foot/ankle the latest and possibly worst (not counting breaks) has been the collapsing of my heal. (yeah i know???) During a skate contest in the middle of June i took a slam on my heel and flattened out the heel and completely destroyed the muscle. now i get shots of jelly in it?!?! making me feel like i am walking on a sponge. im now on my 3rd week of a 5-6 week of full recovery.
