Have you been tested for Celiac Disease? It can be silent (no GI symptoms) and can cause a ton of other symptoms. It’s not uncommon to have another autoimmune disease in addition to Celiac Disease. I was silent celiac and had small fiber neuropathy, osteoporosis, joint pain, ataxia, allergies, etc. I’m now gluten free. The ataxia disappeared. I still have the SFN and osteoporosis. I take Dupixent injections for the asthma and sinus issues. Might ask your doctor is you could have a blood panel to test for it. Just a thought.
