Should I change doctors? I have had widespread pain for about a year now and my doctor does not seem concern.?

I asked him to run some test to see what's causing the pain and he said it just RA. So I asked him to refer me to a rheumatologist he said I have to wait until he does some lab work and a MRI before I can see one. Then he gave me some medicine called methylprednisolone and thats the last i have heard from him. I don't think he cares. What should I do.
