Q I have an undefined scratches in my both under arms
This itching underarm is medically known as pruritus. The symptoms experienced due to itchy armpits vary according to the underlying condition. You may experience itching accompanied with redness, soreness, swelling and scarring. Scratching the itch may temporarily relieve the symptoms, although it can cause an infection through the lacerations caused by scratching. Unclean hygeine, candida infections, inverse psoriasis, dermatitis may cause this. The deoderants and antiperspirants may cause the pruritus as it is directly applied over skin. Itching under the armpits is not natural and should not be ignored. As it is treatable, if you are suffering from this condition, it is best that you seek medical treatment to prevent discomfort associated with this irritation.
