There are other things that can cause those symptoms.
You may want to follow up and get a full thyroid panel. Not just TSH. Peel back the layers of the onion as they say.
Yes other things can cause these symptoms but when having EVERYTHING else ruled out it kinda leads to my thyroid, all lipids are fine, went to a gi doc that tested for everything under the sun, endo scope and colonoscopy were done as well. Hormone panel came back perfect beside the elevated TSH. And like I said TSH has always been perfect prior to taking way to much arimidex and crashing my e2(e2 was reading below 5.2 for 3 months straight) I also have high blood pressure and high pulse constantly. Never an issue in the past prior to crashing my e2. Even on a gram of test my blood pressure is never elevated. So I'm guessing my e2 being so low for so long caused a increase in thyroid which is giving me all these night mare side effects.
