It depends on how much you're using your arms! Do you have a job or are you doing an activity that requires moving them a lot? Then likely so, and I'd look into things that could help with the pain (one of those back massager wands that you can plug in and stuff!). Otherwise, I'd seek help from a professional like a chiropractor or a doctor that is aware of your POTS and how it works.

I have it with my TOS and CMP but I don't know about POTs i have a friend with that except she is 430am right now so too early to write her and ask

I also experience this! Dunno if theyre connected but i have what seems like chronic (since i was 12/13 til now at 21 still) and pots.

Are you hyper mobile I talked to my physical therapist and she said my shoulder pain is likely due to my hyper mobility

I'm not saying you have or don't have this but look into intracranial hypotension

i have pain in all different joints in my body from POTS or possibly something else. it’s very frequently in my shoulder but that’s from an old dislocation

I have it but I also have hEDS, which causes joint subluxations.
