Since about Saturday my right arm has been feeling weird. First it was the top of my forearm...it felt kinda achy. Today has been the worst I guess you'd say. Most of my arm has a cool tingly feeling...it's not cool to the touch, but it feels like my arm is being air conditioned or something, and it's kinda achy off and on. I've not lost any use of it, and sometimes my muscles feel sort of tight. I started working with weights a couple weeks or so ago, and I thought it might be that, but my left arm doesn't really feel any different, and my right arm is my good arm so of course it gets used more. Any ideas?
