Open Question: squash left knee pain
hi im a 17 year old male i play squash regular about 2-3 times a week, i consider myself very fit and athletic but sometimes after ive played i get an aching pain in my left knee its not really painful but it is annoying and hurts a fair bit, anyway it goes away after a couple days or so, but i just wondered why i get this i think its simply just overuse? i dont think its my footwear i use prince nfs indoor II shoes and there fine. anyway ive just played 3 days straight quite vigourously and now ive got the same problem, and it seems abit more painful this time, anyway does anyone reccomend any knee strengthing exercises or should i just simply take a day or two gap between matches?
thanks for any input
