I had symptoms for several years. I was convinced I had it. However, every doctor I saw said I didn’t have it. This included rheumatologists, ophthalmologists, dentists, and I can’t even remember them all. Finally, I saw a new rheumatologist after I had been doing a lot of research on Sjogren’s. What I found is about 30% of people with Sjogren’s are seronegative. This doctor was kind and patient. I told him I had read that having a lip biopsy was the only definitive way to find out if you truly have it. I had to find this out myself, as no doctor ever even mentioned it to me. He agreed to order one for me. Sure enough, I definitely have it. It felt like a weight had been lifted off of me. Someone finally believed me. Since then I have been able to get the proper medication and care. Unfortunately, though, that kind doctor left the area, and it has been very challenging to find a really good one. My suggestion is to insist on a lip biopsy. I did not find it painful, as so many say it is. Wishing good luck to you.
