Any ideas what went wrong? I haven't worked out much for a while but I love to get back my stength. I can't do push ups, because when I try, a shooting pain from the palm of my right hand appears, I purchased some push up bars to help cushion this but the pain is there, but not as bad.

Also, I'm considered strong as i can lift heavy objects, but when it comes to arm wrestling, I have absolutely no power!
