I have been on methotrexate for over a year due to RA and it also helps alleviate my SS symptoms. As I live in a developing country this has been managed by a team of doctor friends who are not specialists. I went to my first rheumatologist as I figured I needed someone to oversee this who was experienced even though I am doing really well and have few issues these days (while on methotrexate). As nothing showed up on the tests she said it was all psychosomatic. This is a doctor in Malayasia and I hope no one else gets this treatment!
