I read your post and wanted to give some information on a Comprehensive Covid 19 Center here in Chicago. I lost my taste/smell with Covid in December of 2022. I also had brain fog, balance issues and hives that came and went, along with being oh so tired! I was asked by my daughter to have my Thyroid checked and do a blood test because I think she noticed I was gaining weight, daily! To my and my doctor’s surprise, I had over the top numbers for Hashimoto’s and Hypothyroidism. Never before did I have this! I began taking Synthroid and Cytomel and have now weened off the Cytomel and just take 75 mcg of Synthroid to control my hypothyroidism. I have eliminated eating Gluten, Dairy and Soy due to my Hashimoto’s. I read a book by a doctor Izabella Wentz, M.D. on Hashimoto’s and she suggests eliminating those 3 foods and I did and lost the bloat in my body and my brain fog is just about diminished. I have also lost some weight. I will be seeing this Covid Clinic in April and wanted to share the number in case you’d be interested. Their number of 312-926-9900. I wish you well on your health journey.
