I'm in my early thirties and have had RA for 6 years. Have been on sulfasalazine for 5 and, for the most part, it keeps my arthritis under control. I feel well, quality of life is good, work full time in a busy, stressful job and feel like I want this to continue and feel 'normal' for as long as possible. However, my rheumatologist has suggested that my condition is "more active" than she would like and wants me to add methotrexate to the dose of sulfasalzine. I would like a family at some point and know that methotrexate can affect fertility and reading about the way some people feel on it scares me. I don't want to tip the balance and feel ropey by starting on it, but feel like I should trust my doc. What have peoples' experiences of MTX been like? Is it worth the side effects, etc? V uncertain about what to do.
