Could I have a thyroid condition?

sounds a lot like a thyroid condition. you also exhibit a temperature intolerance, which is another symptom. i have reverse T3, which acts like an autoimmune thyroid condition, and i actually bounce back and forth between symptoms of hypo- and hyper-. the symptoms you have now all sound like what i have when i am at one end. definitely see your doctor. right now my doctor has me on natural thyroid, iodoral, fish oil, b-complex and a multi-vitamin. a lot of regular doctors won't do the extensive tests and i had to see a natural medicine doctor (not a quack, someone who is actually an MD and later went on to study naturopathy among other things). keep track of your weight, how much you sleep, and what you eat. good luck!
