I was diagnosed as having hypothyroidism about a year and a half ago. They did a thyroid scan and ultrasound, and dais I had a small goiter/nodule. I was not put on any meds. at that time. About a year later I was in the hospital- due to depression, and they said my thyroid levels were off and put me on a low dose of synthroid. Last month, I had run out of my synthroid, and my hair started falling out, I was having night sweats, severe fatigue, and pain and tenderness in the thyroid area of my neck- my glands in my neck were swollen too. By the time I got to see a doctor at the health department, the pain and swelling had left. She said I was probably just coming down with the touch of something, but went ahead and wrote me a refill on my synthroid. Here I am a month later, still taking my meds, and my neck started hurting suddenly again and is very tender to the touch, and with movement. Should I be overly concerned? A friend of mine told me I should go to the ER asap. But I'm not sure if it is that serious, and whether I should just wait until Monday and make an appointment at the health department (but they may not see me right away). Any suggestions??
