First off, I’m so sorry you are suffering so badly. I can’t even imagine…, but kind of. I contracted Covid in December of 2022 and have not had any smell or taste since. I’ve had 3 Stellate Ganglion Block injections and have had only slight success with that. I’ll be having a 4th Stellate Injection on June 13th at our big hospital, Northwestern in the city of Chicago. I can smell the ground coffee in the morning on most mornings and am able to smell other things on occasion. I do taste salty, sweet and sour but no flavors of anything. I’ve done smell training with different essential oils and test myself daily for both smell and taste. It’s been quite awful, to say the least, but the only good side is that I’ve lost some weight. I wouldn’t recommend doing it this way! I am going to suggest to you because you talk about extreme fatigue, having your Thyroid Levels checked. It’s done through a blood test and what you should ask to have done is a complete Thyroid Panel, testing TSH, T-3Free, T4-Free and your Thyroid Antibodies. Since you seem to be fatigued often, you could be hypothyroid, which I also am, along with having Hashimoto’s. I have given up Gluten, Dairy and Soy due to the Hashimoto’s, which seems to trigger my inflammatory symptoms. I am feeling much better that way, but this no taste and smell thing is not much better. Before I was diagnosed with Hypothyroidism, I felt extremely fatigued and my blood pressure was quite low as well. Since starting on Synthroid which is the medication I take for Hypothyroidism, I’m back to having a normal B/P and don’t feel tired all the time. I now can walk 4 miles 3 x’s per week again and do light weight training. I should also state that I had a mild case of Covid, but my sinuses were extremely plugged. I’ve been to an ENT and he told me there are no blockages, but my ears feel full most days. I was also told by my Functional Medicine Doctor that I have a lot of histamine in my body. I’ve eliminated several foods that I found I was sensitive to, but still am not tasting and smelling.
I wish you success on your health journey and please post an update on how you’re doing.
