I allegedly had this. I say allegedly because my GP never even touched my thyroid, my severe symptoms were over when I finally saw an endo, and 8 months later my GYN told me this is what I had. The hyper symptoms lasted three weeks for me. I also had a sore throat, brain fog, my fever was only low grade, a quick 7-lb. weight loss in three weeks while eating a lot, anxiety, memory problems, and elevated BP. After three weeks the symptoms just sputtered. At about six weeks I started noticing hair loss, quickly gained weight back. It has been two years and I have never felt "normal". I feel much better than when the whole episode started but seem to go back and forth with the fatigue and really having to watch my weight, to the other end of the spectrum, where I seem to be now, having anxiety, higher pulse rate, and can be more liberal with my diet
. The hair loss is driving me crazy because while I am losing it, it is also growing fast which means I have all this uneven growth. I think most people do better overall with an acute thyroiditis and the symptoms usually completely go away. Hope you feel better soon.
