I thought my shoulder and arm pain might be serious as I was feeling it in my left arm. I went to my doctor who sent me for a complete workup to check my heart. It was coming on gradually over a long period of time, so it was not like that sudden pain in the left arm that comes on quickly or gets worse with activity. I ended up being diagnosed with frozen shoulder. It took almost two years to feel better, and then I had to go to aSacramento chiropractic office office for some therapy on my back.
Over the two years I had the problems with the frozen shoulder, I had adjusted how I moved my left arm.
