Swollen legs and feet

I have been struggling with chronic pain for over 10 years. I was diagnosed with fibromyalgia, have arthritis all over my body mostly in my knees, rotator cuff damage in both arms, neuropathy and recently diagnosed with polymyalgia rheumatica. I am tired all the time, from when I step out of bed in the morning and then many nights can't sleep an uninterrupted 6-7 hours. My skin is always itchy and sometimes breaks out in rashes. I am in constant pain and take tramadol 50 mg 2x a day for pain and methylprednisone 4mg for the PR. Recently my legs and feet have been swelling and I was given bumetanide 1mg for fluid. However, this does not bring the legs down much. I have to walk with a walker and find it very painful to go from room to room. My problem is that I do not know what kind of doctor to see to begin with. Cardiologist, neurologist, rhematologist, vascular, etc, etc!!! Could anyone point me in the right direction? I am a 76 year old woman and live in Florida. Thanks for any help. PS, I prefer to take natural remedies instead of drugs.
