I know nothing about thyroid issues...I was just looking around to find answers of my own and stumbled across your post....but I was just wondering, have you been assessed to see if you have sleep apnea ? I have all those symptoms with mine from loss of oxygen during the night. I left it untreated for so long that now I also have fibromyalgia because of it.
You say that you wake up feeling nervous...I wake up several times a night with palpitations because when you stop breathing during sleep, your brain will send a rush of adrenaline to wake you up to take a breath...making you feel nervous and have heart palpiations.
I get the aches and pains and dizziness from the loss of oxygen at night...I also often have shortness of breath.
Anyway, I just thought I would give you something else to look into because most people don't know that sleep apnea can cause alot of terrible symptoms.
Feel better soon !!!
