I have been itching all over my body for several days now...nothing has changed as far as detergants, soaps, shampoo, no changes in diet....what could be causing this? I have hypothyroidism....take synthroid daily....another problem that is embarassing, I sweat from my head so bad that it drips from my hair...this is an everyday occurance...If the tempature is above about 68 degrees, it is really bad...Thank you for your input.
