Hello,
I am a 24 year old female. I engage in a physical activity called Crossfit, which is a mixture of Olympic weight lifting, gymnastics, and track and field. I woke up this early morning to my left arm hurting so bad I couldn't go back to sleep. It feels like a dull ache, or someone punched me in my deltoid. The ached travels all the way down my arm, and is causing grip weakness. I tried rolling on a foam roller, lacrosse ball, and icing it. The pain is still there. Could this be a pinched nerve?
