Glad you found us!! So glad you decided to post. More folks here know more about
labs and such than I do. I get some info from Labtestonline.org
I know a lot of the lupus symptoms overlap other autoimmune diseases too. Sometimes its really difficult to differentiate between diseases. Your treatment, though, sounds like a great start. Your labs (RA factor) does point to Rheumatoid Arthritis. The folic acid may help with your mouth sores too.
Hopefully some of the others will be along to help with your other questions too. The MTX will work better after you've taken it a few times. Do you feel any benefit yet??
There are some helpful links at the end of my signature if you'd like more info about
