I first noticed it bowling last October. I felt the discomfort in my right forearm, but was tolerable to bowl. The pain in the left arm came soon after and bothered me all summer and more than the right does. It doesnt hurt my right arm to bowl this year yet and making that motion, but when I bend the left arm to help steady the ball, I feel discomfort.
Holding the phone up to my ear,with either arm, I feel slight twinging, but it hurts worse when lowering the phone.
When my arm is fully extended, and I try to pick something of weight up, I feel a lot of pain in my forearm.
