How long have you been n the Tirosint? It may take a while for the change to make a difference in the way you feel.
Armour also has fillers/binders and dyes...
We might be able to help you better if you post your current thyroid labs with reference ranges so we can get a better idea of what's going on.
I, too, have severe breathing problems, now. Was on Levothyroxine for many years, but am now on Tirosint. My Doctor thinks I may be sensitive to the dyes and fillers in the Levo. So far, I can see no difference. I would like to try Armour.
Try to 'illiminate' if possible.
I suffered with anxiety for years and had problems with breathing.
I still get the odd occassion when I feel I have to take a 'big breath' but I know that is anxiety creeping up on me (usually if I overwork and am tired).
My way of getting rid of that symptoms now is breathing exersises.
Breath in to the count of 3, HOLD then blow that breath back out on the count of 3.
Your talking to someone here who suffered from 26 years of Agoraphobia, Post Traumatic Stress Disorder (Husband committed suicide by hanging) and severe panic attacks.
I conquered the Agoraphobia before being diagnosed with Graves and it came back. But I have fought on and seem to be winning the battle.
Maybe it is anxiety as this Thyroid stuff can send anyone nuts lol.
I can only make guesses as I dont know the severity or level of your anxiety but the best thing to do is 'illiminate.'
Personally myself, I am on 0.50mcg tablets of thyroxin (0.5mg) and have had no problems with it but its made in Australia and has a different drug manufacturer than the USA.
Hope that helps a bit.
Let us know how you go.
I was on .088 mg for years and my thyroid ended up overactive. Adjustments were made with medication eventually to .05 but that wasn't enough and I was getting really tired compared to when it became overactive. It was adjusted to .075 mg but was having bad side effects to Levothyroxine mainly the breathing. Then I was on Synthroid and side effects were terrible. Since I stopped taking it last Thursday the side effects have dissapated but still having some breathing difficulty. Not sure if it's anxiety since I am on Xanax but my breathing was worse on Levothroid. I guess my T4 was at 9 and is now down to 5 so it's getting closer to where it should be. Problem is I'm afraid to take the brand name Levoxyl since I think I had difficulty breathing on that at .075. Wondering if I should get my RX filled for using two .05 taking 1/2 of one to make .075 since .05 is dyeless. Problem is I don't know if it's just Synthroid .05 that is dyeless. I also have Crohn's disease and fibromyalgia as well and now in perimenopause. I will be taking Prempro but am holding off until I get this thyroid situation under control and just in case I have side effects from Prempo. Need to be able to decipher between meds.
The only time I have had trouble with breathing is when I am heading Hypo.
What were your last lot of levels?
And by the way...let the Docotr think what he wants.
If you are not well, you are the first to know as you know your body better than others.
