Trouble Sleeping with Hives

I'm a 54 year old woman who has been diagnosed with hypothyroidism and has had chronic urticaria for almost 3 years now.  I've been to several general practioners, an allergy doctor, skin specialist, immunologist, and gyno...and no one seems to know what's going on or care to do testing to find out.  I've been on Levothryoxine, benodryl, zyrtec, xysal, prednisone, Zantac, Atarax, etc...and I still have the hives just about every day from head (angiodemia) to toe.  I have a hard time sleeping because I wake up in the middle of the night itching.  I'm afraid to go to sleep for fear I will wake up with them. After reading this site...I'm going to try Synthroid instead of Levothryoxine and see if that helps at all.  

Just a little history that might help: About 24 years ago when my youngest child (of 2) was 4...5 years old I developed hives for about a year...but they weren't as severe as they are now.  Whenever I had a sinus infection or other bacterial infection and was on antibiotics...the hives would disappear.  I went to many allergy specialists at that time but none of the doctors wanted to give hormone tests, as I wasn't diagnosed with hypo until about 5 years ago.  The hives just disappeared and didn't reappear for 24 years.

It's a little comforting to know that there are other people like me...I haven't encountered anyone with this disease in my life.

Does anyone have sleeping problems and what do you do for it?

Are there any itching remedies?

Thank you for listening.

Insomnia is a common symptom of thyroid, I started having sleeping problems in Sept of 08 and thats when I was first diagnosed wth Hypo from blood work, I take Lunesta#2 and it gives me 6 hrs most of the time, this was prescribed by my Endo, I had a GP prior to that, this clown thought I was depressed and put me on Trazadone, I said no thanks.
I don't know anything about hives being a symptom of Hypo, I have had a lot of the symptoms and (Knock on Wood) have not had that one, On and off Depression and anxiety, Muscle aches and muscle cramps, short tempered and brain fog, its a gauntlet some times. I was also on Generic Levothyroxine and it did nothing much for my TSH, when my Endo switched me to Name brand Synthroid I had a pretty good drop in TSH, You might want to post your thyroid labs here and other members will explain them to you, also if any have had hives they may offer advice or treatment. Good Luck FTB4
