TweetA couple of months ago I was lifting a rather heavy object at work. Using a grip and lifting upward with my left hand. I immediately felt pain in my forearm. I thought I just pulled something, but I'm not so sure now what I did. I can not flex my bicep. Trying to curl without assistance is impossible and I get no squeeze in the left bicep because, well, I can't flex the muscle. Constant pain just below the inside of the elbow joint. Did I tear the ulna nerve? Did I separate nerve from bone? Any input would be greatly appreciated. This is gettin worrisome. I know I'm not helping my cause by continuing to work out with it...but I'm kinda in the middle of sumpin(feel me?) Thanx in advance
