I just can't seem to catch a break! Weight training (and overdoing it) caused some issues in my arms which aggravated a pinched nerve in my neck. Due to my unconscious efforts to compensate for the pain, I now have tendonitis in my shoulders/upper arms. Ever try to heal from tendonitis? They tell you to rest the affected joint for a few weeks. Uh huh. I'm a busy mom...and I can't do what I do with just one arm.
