Thank you all for your replys.
I'm not sure if this is due to being hypothyroid or not because I've had this symptom even when my levels were normal. I didn't think about my being intubated for my surgeries having something to do with it. I'll definatly talk to my Dr. about that. Also, I didn't realize that shortness of breath was a TMJ symptom. I do have TMJ, but it's not severe.
My other symptoms include: chest pressure, lightheadedness, a few fainting spells, fatigue, backaches, and a very rapid heart rate(even when I'm hypo it's over 100). I've had every cardiac test imaginable including a heart cath, so any heart related problems have been ruled out. I've also had numerous other tests, so the only things my Dr.'s have left to blame this all on is anxiety and my thyroid. I've been on every dose of synthroid between 100mcg and 150mcg....and all of my symptoms have stayed constant through every dose. I never imagined having my thyroid removed would result in so many problems. Before all of this...I didn't even know what a thyroid was.
