@kaprizzz Welcome to Mayo Clinic Connect! Everyone on here are looking for answers while they help others with tips and help. Please don’t say that you’re convincing yourself that it is nothing. It IS something and you deserve answers and help. The doctors (internal medicine) who didn’t know what you had and wouldn't give you a referral are, unfortunately, common in health care. Can you go to your primary care doctor and ask for a referral?
You might also try calling one of these hospitals and asking if they know of a rheumatologist near to you

Please don’t give up! Will you keep me informed of what you learn?
