I have Hashi's. My last TSH was 3.84 and I am on a higher dose of Synthroid trying to feel better. I started on Synthroid in Sept and have been on different doses since then. I am currently on my 9th bad cold since December. They have all been prolonged and wipe me out like the flu. I had a ACTH test several weeks ago - my endo said it was normal (I had all adrenal fatigue symptoms and fainting episodes. He tested b/c of that and the colds I described). He also said I was normal at 3.84 TSH even though I told him how awful I felt @ 3.15 (for 2.5 months). I begged to get .075mg so he said OK, re-test in 5 wks. I still feel crappy but it's only been 3 wks. Anyway, I'm wondering if something else is wrong with my immune system and what tests I could have done (with a different doctor). Was anyone hypo and had tons of prolonged colds? I'm SO tired of constantly having colds. I was actually healthier before I started Synthroid. I'm just wondering if this will stop when I finally get the right dose or medicine, or if I should consider other causes. Should I just relax and see if this will stop one day (although who knows when I'll get the right treatment!) when my thyroid is OK???
ETA - I've been eating healthier, taking a multi-vitamin plus selenium, zinc, B complex, etc. and am still always sick.
The winter after I started treatment and was still trying to get adjusted, I had 3 colds, 2 sinus infections, and some kind of unidentified respiratory bug. The winter after that, after I was more thyroid-stable, I had no illness at all. This past winter, I had only one cold.
It should get better for you, too, with patience and time.
