I have right shoulder pain. I am right handed. The pain mostly extends down the front of shoulder towards bicep. However, there is some pain extending down back of arm as well. It's sore all the time, no swelling. Hurts the most when I extend my arm. I have been a consistent weight lifter. But I don't remember any incident where there was pain. I have not lifted in two weeks. I am a coach so I have thrown thousands of passes in my life. None this year though. The shoulder just feels lose when I stand and let it hang.
