I went from a normal TSH count in November to great than 13 in December. I was put on 100 mg levothyroxine and felt good for 4 months, then started to get horrible headaches, my muscles ached, the joints in my legs hurt, was extremely fatigued and not able to sleep. After a blood test, I was told the 100 mg was too much and I was dropped to 75 mg and was told I have Hashimoto s Disease. I ve since developed a goiter and am feeling no better. I m ready to try something else. Is there any truth to the claims on Actalin?
