Just under two years ago, I completed radiation for cancer of the mouth and neck. In the last 6 months I have noticed that I am increasingly fatigued. In the morning I was mine, now I am getting more fatigued. When the symptoms first started, I would begin getting tired around lunch time and be dragging by the time I got off work. Lately, I am tired from the moment I get up. My mind is foggy, I'm always forgetting things and just feel like I'm walking somewhere in the clouds. I also have been having a hard time dealing with everyday stressors. I feel like I'm about to have a nervous breakdown over things that normally would not have an effect on me. I stay cold in my hands, feed and nose, until I go to sleep. After I go to sleep I sweat. In addition, I have had 3 blood tests, two of which have shown my TSH level is high and my cholesterol is high. I am currently awaiting results of the 3rd test. Do you think I could be hypothyroid? Could these symptoms be fixed with medication? I just want to feel normal again.
