Talk to Dermatologist on Skin Allergy Severe With Watery Black Head Pimples

My mother is currently experiencing a skin allergy on her neck and arms, which is characterized by redness, pimples, and a burning sensation accompanied by waves of pain. Despite utilizing various anti-allergy medications and antibiotics, her condition remains unchanged. Additionally, the pimples have become black-headed due to scratching. The medications that have been used include Kestine, Neo-Antil, 1% Hydrocortisone Cream, Priton, Azomax, and Augminton.
