Dear Doctor
Skin burns, becomes red first under arms and legs joint, itchy skin, and than becomes white and abrases.
Dear Patient
The redness, and itchiness are suggestive of an irritant contact dermatitis to something that you may be applying to your armpits like a deodorant.
Irritant Contact Dermatitis Treatment
The treatment of irritant contact dermatitis is as follows:
1. Clean the area with tepid water.
2. Apply a mild steroid cream like 1% Hydrocortisone twice a day for 5 days.
3. If the itching persists, consider taking an anthistamine by mouth. Examples include the non-sedating fexofenadine (Allegra) and loratadine (Claritin) as well as the less sedating cetirizine (Zyrtec). The sedating diphenhydramine (Benadryl) and hydroxyzine (Atarax, Vistaril) are also used to reduce the itch if it disturbs sleep.
4. Do not let the irritating substance come in contact with your skin in future.
