Ihave been on Levoxyl for about 2 1/2 yrs now. I am now taking 100mg. I ache in my hips and arms and sometimes have a sore throat. I have gained weight (about 20lbs) and feel confused and almost like a panic attack at times. My vision is shot and now I'm going for laser surgery. My libido have been effected by this too and that has caused problems. I have not lost any hair but my hands swell from time to time. Please let me know if anyone has any suggestion for this. I don't want to stop taking it for fear something will happen.
