Hello sorry for registering just to ask this one question on here but this seems like it could be solved quite easily if I have a better idea of what is causing it and why. I don't know anything about shoulders other than it's a ball and socket joint.
For the past few days since getting a new chair I have been getting quite bad discomfort in my right shoulder whenever I sit down for too long and am baffled as to what might be causing it. It only really seems to happen when im sitting down and it wouldn't be as baffling if it didn't happen no matter where I put/angle my arm. I am questioning whether it has something to do with my neck.
The reason I mentioned my new chair is because it is noticeably much less firm and supportive as my last one and I was thinking it might have been something muscular even though it feels like it's the joint. the last time I tried sleeping round a friends house on his giant bean bag I woke up and my neck felt really bad so the 2 could be related.
But no matter where I put my arm when I am sitting down the shoulder will start to hurt after a short while (sometimes even when im standing) and it does seem to be getting worse so it can't be just "oh I just need to stop sitting like that", im not sure whether ive injured it recently without realising or what but any advice on things I can try to remedy it would be greatly appreciated it is getting worse by the day.
im a 22 year old male btw so I doubt it is arthritis.
