I have dry eye, not taking estrogen. My rheumy says it's also common in RA and AS. Mine started after I took Plaquenil - - which has a side effect of causing eye problems. Perhaps that's the link for me. But I have more than dry eye, I have Sjogrens now, which means dry mouth and it could be affecting the fluid in my joints. But interesting to know, the more we learn about these things, the better off we are.
