Not everyone gets every thyroid symptom and sometimes they're paradoxical, like I gained weight with hyperthyroid. In fact, I didn't have most of those either. I got cold, sleepy, no energy, low appetite, weight gain.

On the other hand, a pituitary problem could cause TSH to be elevated too. It is the pituitary gland that secretes TSH and I've heard hard bumps to the head and make it screwy, or tumors.
