I take methotrexate 2.5mg, 4 on Tuesday and 2 more on Wednesday for rheumatoid arthritis. With that I have to supplement B2/folic acid daily. I'm lucky that my GP checks the RA markers @ blood work and writes the script for me so I don't have to journey to visit the rheumatologist. His office is up on 2nd floor of the hospital. Farther than I can walk.
At one point the sciatic nerve pain down right leg and across that foot was so bad that I had my daugher drive me there and roll me to his office in a wheelchair. That's the day I told him, "I'm not a bird. You want my money? Come down to the ground and I'll come see you".
I haven't been back.
