Well, you really seem to be between a rock and a hard place. You really need another doctor to look at this objectively...and I agree an addition site of the skin biopsy would prove helpful.

Frankly, starting the methotrexate is backwards to protocol. They should test FIRST for the Sjogren's, not AFTER taking it. Methotrexate can possible alter the result of the lip biopsy...as it's an immune suppressant. So your results may come back negative when you really may have Sjogren's and the methotrexate is masking it.

Sorry to hear your options for medical care are so limited. Have you tried some of the supplements listed on the stickies to see if you get any relief?? If not, that would be the place to start.
