Pick your brain if I may. I was diagnosed about 9 months ago and as well as 125 Levo I take vit d, b12, selenium, liquid iron, vit c, zinc and a good b complex. . Just had my first cold since then which was in my sinuses and very painful and infected. Kept away from the doctors and antibiotics and just dosed on pain killers and Sudaphed. Head much better now but feel like I have been run over by a truck! Achy muscles and tired. is this normal?
