Hi, My oh Chris has been prescribed 50mg levothyroxine by a specialist and has just taken the second day's dose. Yesterday he had a migraine (not unusual for him but he felt there was a connection with the new medication). Today his temperature is down to 35.0. Previously it's been low, 35.4 and up to 35.6 but never this low. He says he feels horrible. I'm just running him a hot bath. Does he need urgent help do you think? I've posted his results previously and will post again if it helps, but I'm struggling with a slipped disc so hard to type right now.
