Just about 3 weeks ago I started having the same thing. I'm not allergic to anything... However, a few days before the itching, I did have an increase on my thyroid medication (synthroid 125mg). It started out as small red bumps on my hand... but after I took a shower it disappeared. I didn't think much of it at the time, I thought it was just a random irritation from me sleeping on my arm. But as time went by, my legs and upper arms became itchier and itchier. Now it's on my chest, stomach, legs, arms and neck. I tried Benadryl and Claritin in combination to Hydrocortisone cream. It's only been a few days, but nothing is working. I feel that the more I wait to have it checked out, the worse it will get. I've never had anything like this before, and my skin isn't sensitive to anything. The only thing that has changed in my life was the medication for my thyroid. I Google'd rashes and hypothyroidism, and there's quite a few people who have similar issues. Unfortunately, I'm a college student living 5 hours away from home, so I won't be able to see my regular doctor. Any help would be greatly appreciated... I'm about to rip my hair out!View Thread
