I too developed Hashimoto’s and Hypothyroidism after having Covid. I now take Synthroid to help with that and it has helped. Also, because I have Hashimoto’s Thyroditis, I have eliminated gluten, dairy and soy from my diet and I feel so much better and have even lost weight. Give it a try, you won’t regret it. Have your Thyroid checked by doing a blood test on it. Talk with your doctor and ask him to order a Thyroid panel. It’s an eye opener! Good luck!
