question: Hey, so last week i crashed my longboard and it was pretty bad. I had tons of pain and my arms were pretty banged up. About two hours later i noticed that i had little to no flexibility in my left arm and hurt to move it. Now i have almost all my road burns healed. But my left arm is still weird. I cant fully straighten it and when i do a bicep flex without flexing (if that makes sense) i cannot pull my arm towards my self. What do you think..
