I'm needing more information on how methotrexate helps with arthritis if I am already taking humira for last 7 months. I have psoriasis and arthritis but humira is not helping with either one. I had both before humira but last 6 months arthritis is worse. Rheumatologist wants to start methotrexate but I've read so many cons and some pros. Not sure what to do: In a way, I think I can live with the arthritis but sometimes it just keeps me from doing what I want and I am limited. At other times, it doesn't bother me. I guess I need some insight. Anyone else that has started methotrexate and it relieved arthritis? I'm a little scared to start on another medicine.
