A few months ago, I tested 15 tsh
and my dr started me on 50 mcg
levothyroxine. After 8 weeks I retested
and my tsh was 7, normal range being below 4. My dr increased my dosage again to 75mcg. Soon after this increase I started noticing hives. Hives cover my torso, thighs, buttocks, and they are large welts, extremely itchy. I thought it was the levothyroxine so I switched to synthroid. This change had no effect. I saw an allergist and did a scratch test with everything coming back negative.
