I Had Dermatomyositis As A Young Child. I Have Been

I had dermatomyositis as a young child. I have been having problems now and because of my age I get that I have arthritis. Now I am sure I do but I feel that so much may have been due to this disease. I have talked with two rheumatologists. One told me to take 16 Ibprophan a day and the other said I had arthritis. No comment and no help. I need a doctor in Portland Oregon who has dealt with this disease.
