You need to see a rheumatologist. How you get to that point depends on your insurance coverage. I was diagnosed officially with arthritis at age 30, but I'd had symptoms since childhood. I, like you, sought help when the pain became really bad. My daughter has the same symptoms and she is only 9. As to your other question, if your pediatrician isn't paying attention to your child's health concerns, find a new doctor ASAP. Best wishes.
Hi there! My first reaction, when a doctor won't listen to me or my concerns, is to FIRE HIM and find another doctor who will. Your instinct is telling you something is wrong with your body, and maybe that of your son. Follow it!
Go to your family physician and ask for a referral to a rheumatologist and don't take no for an answer. You may be able to find one who will treat both you and your son together, but you may also have to take him to a pediatric rheumatologist who specializes in treating kids.
Rheumatoid arthritis and its *many* autoimmune "cousins" manifest in different ways in individual patients; there is no one size fits all in terms of symptoms, how aggressive the disease becomes, which joints are affected, and which treatments work.
Most of all, the long-term affects of even low-grade inflammation (that pain you can "live with" but not get treated) are becoming more and more well known. It can affect the eyes, internal organs, even lead to heart disease. So joint pain, in the long run, is almost the least of your potential problems,
Tell your and your son's doctors point blank that you need a referral to a rheumatologist NOW, and if you don't get it, you'll find one on your own and he can just eat your dust. ;) YOU are your own best health advocate. No one, not even a doctor, can take care of you better than you can.
Hang in there!
