went to my friend's lake house and went water skiing and knee boarding. had a few crazy wipe outs. but didnt notice any immediate arm pain. today in the gym my left arm feels weak as hell. mostly the bicep. i prolly just strained it so im taking a few days off and might ice it and take some advil. hopefully i'll be better in a few days. dont really have a question. just wanted to vent cause i Hate gettin injured.
