Signs of skin irritations caused by an allergic reaction include hives that produce welts or red bumps and a rash that itches and burns due to contact dermatitis, which is a condition that results when the skin is in contact with an allergen or skin irritant such as detergent, soap or shampoos, explains the American College of Allergy, Asthma and Immunology. A latex allergy can produce itching and hives on the skin.
Latex allergies are often accompanied by a runny nose, wheezing, difficulty breathing and chest tightness, according to the American College of Allergy, Asthma and Immunology. Food allergies can cause hives, skin rashes and tingling sensations of the mouth. People with food allergies commonly develop symptoms beyond skin irritations such as swelling of the throat and tongue, abdominal cramps, vomiting, diarrhea or difficulty breathing. People with allergic reactions to food, products or fabrics that cause difficulty with breathing or a drop in blood pressure should seek immediate medical attention. Severe reactions, which are known as anaphylaxis, can result in death if not treated.
People with skin rashes, hives and irritations due to an allergen can treat the skin with cool water and mild soap, notes WebMD. Patients also can apply a hydrocortisone cream to the skin to reduce pain, itching and burning. Painful blisters should be covered with a cold compress for 30 minutes at least three times each day.
