Hello - I guess I'll start with a history of what has happened to me and hopefully the doctor can give me some insight.I am a 28 year old female and after a couple of months of fatigue and muscle soreness I was diagonsed as hypothyroid with a TSH of 18.96 towards the end of July. I am 5'4" and 110 lbs (although I was 120 at the time) and my initial dose of Synthroid was 100mcg. After the first week, I did start to notice a difference physically, I definitely felt better, but was having trouble sleeping and very anxious. I also lost my job at around the same time so that could also account for a lot of my anxiety. After four weeks my TSH was tested again, but this time it was .06 so my dose was reduced to 50mcg. After a week or two, I began to feel like my muscle soreness was returning but definitely not as bad as I was in the beginning. After another four weeks after the dose change, I was tested again and my TSH only rose to .08. That was last week. I am now on the lowest dose of Synthroid they make (I think) 25mcg. I don't know what to make of how I feel - I do have a lot of strength it seems with heavy things, but while whisking eggs the other day my arm felt sore - doesn't seem to make sense to me. My hair loss is also out of control. I don't have my first endo appt until the end of october so I was hoping someone could give me some insight/advice. My mother has also been hypothryoid since her mid forties. Thank you so much - I'm so confused and my husband and I are eager to start trying to conceive our first child but want this thyroid in order first.
