Get a 1,000 mg vitamin D pill and take daily. Get one that is
gluten/soy
free. Walmart has them. Also, sitting in the sunshine 30 minutes a day helped me.
Sometimes, it's not so easy to control the rashes, hives, etc.
Also, I sure hope you're on thyroid meds. Eventually, as your meds are raised, you should be feeling better and maybe these rashes will clear.
My scalp rash actually improved with the prescription shampoo, Nexoral. Then they put me on generic and it doesn't work.
