i was playing tennis this sunday and pulled what i believe is the vastus medialis. i really dont know what i pulled but mostly the left part of my right knee is swollen. a massagist pointed out that at the lower left part of my knee was a muscle or whatnot that was swollen. my friends told me to take ibuprofen and to stretch my leg often. i am hoping to go snowboarding on saturday which is 4 days from today, so what should i do?? is there a possibilty it would heal until then?
