Suggest Treatment For Fibromyalgia And Rheumatoid Arthritis

3months ago I found 7 lumps on my right side of rib cage. Since that they ve turned into approximately 50 now. I ve been told I have fibromyalgia and rheumatoid arthritis. These lumps are very aggressive and very painful. I can actually tell when they will appear by the stinging burning pain. Sometimes I ll have a muscle swell and within 20 minutes there s a lump. They are on my rib cage,arms,top of my legs, lower back, groin, up my spine kidneys,hips...... Pretty much everywhere. All my muscles in my body also burn and swell. In November last year I had my thyroid out and it was cancer. I m not getting anywhere with my doctors. I don t know what to do. Need biopsies of lumps but they keep putting me off.
