Oh my! You are taking a lot but RA is bad to have. I could not take Methotrexate , I tried but had a bad reaction. If your body is tolerating the drugs and your blood work comes back good i wouldn’t worry. I also had breast cancer. My daughter had a mammogram that was clear but she could feel the lump. She has a friend who is a breast cancer doctor and he treated her for an aggressive type. We must be our own advocate. I also have tinnitus and have trouble at higher altitudes like Denver.
Low salt, no aspartame and try some of the apps for meditation with Tinnitus.
Call medicare or get on the website and ask about an IV infusion. They are always helpful when i call.
There are newer RA medications with less side effects but cost more. I understand how you feel. I’m happy to chat anytime.
