When I was at my worst & inpatient at the Mayo Clinic, I was also tested for Sjogrens with a lip biopsy, it was really a nothing procedure. I was also given a sural nerve biopsy to dx my CIDP. They also did a procedure to remove nerve roots from my back, never heard of anyone having that one done; just think they wanted those nerves for research or something, as I was such a bad case of CIDP. They gave me 3 spinal taps, CT scans, 3 complete sets of MRIs, x-rays, etc. all to rule out any other diseases.
When I switched to the UofMN I was told a spinal tap & an EMG would be all they would have done to dx me. But that is easy to say whn they already had the results of all of the tests I had done at Mayo. Anyways, the lip biopsy was really nothing compared to all of the other tests I had done.
Sjogrens is one of the most common “tagalong” illnesses, and many inflammatory and autoimmune illnesses can “trigger” Sjogren’s. It’s very common for it to overlap with neuropathies, arthritis, etc. Read a report recently that something like 70 percent of Rheumatoid Arthritis patients also develop Sjogrens.
