I am so sorry you are going through this! I have had a similar experience from my 1st bout with Covid in June 2022, post Covid shingles in August, then September 30, my right side from above my breast to my toes went numb--when I touched my leg it felt like I had a sheet covering my skin. I felt off balance often then, as well. I've had 5 brain, T and lumbar spine MRIs since and I do have lesions on my corpus callosum and spine that have not changed. Initially, during 4 days in the hospital, along with the first MRI I had a spinal tap where they found no Epstein Barre, Meningitis, Ensephalitis, Guillain-Barre syndrome, Multiple sclerosis was in question, but my neurologists are doubting this. I have one Oligoclonal band, and was treated in the hospital with IV Steroids. I have had numerous blood tests that found nothing significant but a low B12 score; they are not concerned with that and I've started taking supplements.
Recently there have been changes in my right eye vision causing a little blurryness and will be scheduled for an optic nerve MRI. My current symptoms are: Numbness between two toes, and the inside of my right lower leg. As well as an off balance feeling occasionally that I can "right" by touching a wall while walking or lifting my right arm as if I'm on a balance beam. Their current diagnosis: It was an opportunistic infection that attacked my spine while my immune system was compromised by Covid and post-covid shingles. BUT every time I go to see my Neurologist, she looks from a possibility of MS. I stopped receiving vaccinations after the first booster because of the unknown, and since I'm an event manager, I've had Covid 5 times. UGH! I had never considered this Long- Covid until I started reading these comments.
