If you go to a doctor he/she may do blood test to find out whether there is Eosinophilia. In case there is eosinophilia you amy be given a course of tab. Benocid forte or Hetrazan. Itching can also be caused by toxins on the skin (contact dermatitis, such as from poison ivy, poison oak, poison sumac, or grass oils), medications, liver disease, kidney disease, insect bites, hives (urticarial), rare forms of skin cancer (mycosis fungoides and T-cell lymphomas), infections (including chickenpox and fungal infections such as athlete s foot and jock itch), irritation from clothing, eczema, dermatitis herpetiformis, hemorrhoids, and many other conditions, or it can remain unexplained. Infectious causes of itching include sexually transmitted diseases (STDs), parasites (such as scabies, fleas, bedbugs, pinworms, and lice), and viral rashes.
