Suggest Remedy For Rashes On Underarms, Breast And Shoulder

I started with rash underarms, then under breast, then my shoulders stated to ache. this was July. Then my hands started to swell, and got 3 rings sizes bigger, joints all became sore. Knees, elbows ,neck, shoulders, I started taking 75mg. prednisone on Sept 23, wow I can move again, swelling has gone down in my hands. the doctor is trying to go down in the amount of prednisone, I am now taking 35mg a day pain and some swelling is back in my hands. I also started taking a new drug called mylan-hydroxychloroquine 200mg twice a day since Oct 08/14. The doctor was sure I had scleromyxedema, I still don t know lots of blood work, MRI, bone scan, Chess xrays, hand xrays, two biopsy- one under arm and one under breast. I still am in the dark. Can any one help me or may be have a test that could help ????
