Eczema : Eczema, (think extra sensitive dry over reactive skin) gets much worse in the winter, especially areas that rub. The itch associated with this can seem to be an unnatural pain.

Skin tingling: Have a doctor look at the skin on your scalp. I always think of shingles when I hear this kind of story. Often the tingling feeling starts a couple days before the rash appears. This is the time to see a doctor, because the earlier you get started on the medication for shingles, the more it will help. After 48 hrs of the rash, the medicine doesn't make much of a difference. ...Read more
