Hi, I have been having a problem with my elbow , over the last year I have had on and off pain with it, I can t physically straighten my elbow when I compare it to my other arm It is nowhere near as straight, I cannot even push it straight, it is very painful and struggle to pick things up and put any strain on it at all, and is very sore in normal everyday life, as I said it is on and off and sometimes the pain is ok and not a problem but still cannot straighten my arm, any ideas?
