impingement just below scapula, painful right shoulder
I awoke one morning, felt as tho I got bitten, about mid back, below my shoulder blade; a month later, I still avoid pulling right arm rearward; it can trigger a vicegrip like irritatio; extremely painful. A friend mentioned an impingement. I'm not familiar with the term? No visible evidence, confusing.
It's not clear whether your shoulder is also painful; this sounds more like a rib condition. Does taking in a deep breath hurt? If you turn your whole torso to the side, is there pain?
Rib subluxlations, if that's what it is, usually respond quickly to treatment.
