I was like this for a couple of months on & off. I hope somone can let me know something.Sometimes I do have pain,I know my other arm I can’t throw real far, because of the fact I think its damage. When i was little I fell alot. And when I jump or do something using my left arm. It fell like it comes out of place and this strange pain I get causing me to cry like a baby. I had a x-ray on my left arm and nothing was torn or anything. Do anybody know what’s up with my arms. When I take a asprin I get relief from the weakness. I know the doctor told me I had arthritis in my left arm. But now my right is having weakness. What do u think???
