Hyperthyroidism
"I was put on methimazole 10 mg late May.  Within a month, I had gained 10 lbs, my finger and feet became swollen, pressure headaches that would not go away after taking Advil, it hurt just to walk, back pains, and I was soooooooo tired. I complained to my doctor and she lowered the dosage to 5 mg and then she took me off of it after my levels were ok.  Then last week, I&#039;ve had to go back on it again but I&#039;ve noticed that my symptoms aren&#039;t that severe this time but I&#039;m still continueing to gain weight. My doctor says I need to be on it and try to have my hyperthyroidism go into remission.  I hate this drug! I&#039;ve never felt this bad in my entire life but I have no choice but to be on it."
