Glad I found this thread. I was vaccinated in Feb 2022 and in March 2023, I contracted COVID so bad I was in the hospital twice and preparing for end of life. I'm 38 with no history of severe medical issues prior to a Celiac diagnosis in Sept. 2020. After COVID, I would wake up every morning feeling the buzzing/vibrating sensations in my body. They'd last until I decided to get out of bed. I've suffered back issues and have a neck/shoulder injury from an accident 11 years ago. Went through 8 months of physical therapy for my back issues and wrapped that up about 6 months ago. Nothing has helped. I partake in rec MJ on a nightly basis to help me fall asleep. It happens whether I partake or not, so I stopped cessation. My doctors are baffled too. I've been to a GI, Neurologist, have had extensive heart tests and monitoring done. My blood tests show low vitamin D levels which is common for everyone in the winter in NY. I take men's MV, Zinc, B-complex, D, a high quality probiotic for my GI issues, and my doctor has me on 30mg of Cymbalta for nerve pain and anxiety. The Cymbalta has lowered the severity of the vibrations, so they're thinking it might be neuro related. I've been tested for every common neurological disorders (MS, Parkinsons) and every autoimmune disease that affects the neurological system (Lupus, Fibro, Sojourn, etc) all with negative results. I chalk it up to long-covid symptoms now until more data comes out on this issue.
