Cervical issues?

Hello, putting community feelers out because apparently this one has two doctors unable to help me.

For 2-3 weeks now I’ve had this insane pain in my shoulder. It’s mostly isolated to my shoulder cap, probably my rotator cuff. I’ve already been through PT for my shoulders and do exercises as often as I’m able to but at least every week. It’s not fully muscular because I do still get the pain on muscle relaxers.

I’ve seen my primary and ortho, ortho did an xray of both shoulders and checked my mobility (I am hypermobile, so even in pain I’m pretty flexy) and said I was fine.

I need help. The pain gets worse the longer I sit up or stand. And I’m thinking now it may not be my shoulder, but something with my neck. I think this because most of today I was okay, pain varying from 2-5 most of the day. Even hit the gym. But eating dinner at my boyfriend’s, I was jutting my head forward while eating soup. The pain hit so bad I thought I was going to vomit and it triggered a huge adrenaline rush.

I have an appt with an ortho pain specialist, my POTS neurologist, and was already looking into a pain clinic that also happens to do spinal stuff as well. I’m so lost and I don’t want to see these doctors without asking the right questions.
