Everyone that is chronic pain peeps, Yall know exactly whats wrong w/ you sounds like. How were you diagnosed ? They havent told me exactly whats wrong. I have fibro too. arthritis and they said 3 different kinds but I dont know what they are or where at except based on where my pain is. Pain clinic did mention hip replacement to me. One said bursitis in my hips makes the pain worse.
You likely need to see a Rheumatologist for specifics on your arthritis if you need them. I have too many specialists and to be completely honest, I've stopped even trying to see any of them this year. It wasn't really helping much, they just tell you you're broken and give you a bunch of bandaid pills, lol, at least that's how it worked for me. My Neurologist has helped me more than anyone but it will all depend on your ailments and what specialist you need to see. A good general practitioner will know who to send you to.
