This is my first time posting to any type of forum. However, I googled "how long does it take synthroid to take affect" and found this site! I just started taking synthroid a week ago after over a year of unexplained pain and nine months of unexplained weight gain. I went from 118 pounds to 145 and I run, do ballet, yoga, every day. I had depressed me and practically ruined my life. I just want my life back. When will I feel better? When will the weight come off? I'm not myself. Maybe I'm looking for a little sympathy or just encouragement. Any advice or help would be appreciated.
Also, I have had pain in my right hip for over a year. After reading some of the posts, I wonder if it's related to my thyroid. No doctor can figure it out.
