I have been up and down on my thyroid level. I am taking levothyroxine 112mcg for about a month now. My legs get so tight I can't even bend them, they hurt all the time and it is really hard for me to get up in the morning. The pain has moved up into my upper arms. I was taking 110 mcg but I was so tired I could sit down and be out in a flash. I don't know what to do? I really don't think my doctor is helping me at all. The pain in my legs have been going on for 2 yrs. now and it has gotten worse and all the doctor has said is drink water. Please help.
