I have taken levothyroxine since I was 9 or 10 I'm now almost 22. For the past few years my hair has started to fall out terribly sometimes but not always I feel so exhausted all the time and lately the pain in my shoulder is worse I thought maybe it was due to the car accident I was in a few years ago but now the pain in my knees and legs and wrist is worsening I can barely walk the past few days the pain is so bad. Should I be concerned its related to levothyroxine??
