The other day I was working on shoulders and and I felt a bad type of pain in my right shoulder while doing lateral raises with only 10 pounds for a warmup. The previous exercise I did was clean and press and felt no pain.
I am almost 100% sure the reason I have pain in my right shoulder is from a previous job. On the job I had to lift my arm fully extended from the side of my body until my hand was at about head level. This was to grab a light handheld computer.
I did this exact same motion about 500 times a day or more for about 2 years. I also notice that my right shoulder is way less flexible then my left shoulder. Though my left shoulder is unusually flexible according to the remarks made by a family medical doctor. I am right handed by the way.
Anybody have any suggestions? I have decided that I should probably take a week off of shoulder training. It seems clear to me that I have repetitive motion syndrome.
