I have this too in my left arm. The shoulder joint is ruined and necrotic from cortisone shots! Pain runs down to my elbow. I’m told that’s referred pain from the shoulder.

My shoulder pain, running down inside of my arm to the elbow turned out to be a complete rotator cuff tear in the right shoulder. Cortisone injections helped. Sadly, now I need shoulder replacement surgery.

Thanks Kevin Weir. I have now been referred to cardiology. It is still bothering me quite a lot.

Those shots sometimes take a while to kick in. I had one in a shoulder that I previously injured a couple of times. It took about a week and a half to feel better.
