Hi everyone! I have RA and I am on Methotrexate (5) pills a week for about 8 months; however, every time I am trying to walk or use my bike machine I have horrible pain in all of my joints after that mostly starting next dat and I end up in bed for more than four days because I can't move. I am so afraid to get heart disease or become diabetic beside I have put a lot of weight because I am inactive all of this period, but I am wondering is it the medication to cause this pain or the RA disease? Any body experiencing such a condition? I barely can finish cooking the lunch and most of the time just sitting on my chair at work or laying on the couch at home?
