Hi there. Have you been seen for this? Some skin infections are from microscopic insects that burrow into the skin and do not go away without treatment. Scabies is like this, and is very common. The medication for this comes in tubes of off-white colored creams and is available over the counter (OTC), without a prescription. The medication also comes in a spray form and as a shampoo. Otherwise it is important to avoid hot water and drying soaps, as these strip the skin of its protective oils and lead to more itching. Occasionally, widespread itching is due to liver disease, so be sure to see your family doctor for a work up if OTC meds are not helping.
