Hello. I writing for my sister who has a combinations of these two diseases. We have been doctoring for quite some time but NO ONE can address her severe pain in wrists, ankles and toes along with Nausea and brain fog. No matter what they give her nothing works. LOOKING to see if anyone else has the combination of disease that could shed some light for us. We are getting desperate. Thank you inadvance.

i’ve got parkinson’s and my sister has sjogren’s. both are quite bad individually. very sorry to hear your sister has both! i think the medical community copes much better with parkinson’s than with sjogren’s. my impression is that no one really knows how to treat my sister’s sjogren’s.
That sounds really tough to deal with. I’m sorry your sister is going through so much the pain, nausea, and brain fog must be exhausting. Hopefully someone here who has experience with both conditions can share what’s helped them or point you in the right direction. You’re not alone in this, and I really hope you find some answers soon
