One of the most common diseases that appears on the hands is hives. It is an allergic disease, which is manifested by a red rash, often growing into blisters - it resembles burns remaining on the skin from the nettle. From this and went the name. There can be many reasons for the development.
Causes of urticaria on the hands
The most common is direct contact with the irritant - allergen. In this case, specialists can not always find out the reasons why the reaction appeared on the epidermis. It can be food, cream, medicines, hypothermia and more.
The disease is divided into several species, each of which is determined by its own allergen:
- Cold urticaria. It occurs as a result of a sharp temperature drop, which clearly touched the exposed skin.
- Nutritional. Usually occurs even after the minimum amount of food eaten. Most often occurs due to nuts, milk, fish and kiwi. What kind of food affects negatively on the body - depends on the personal perceptions of each person.
- Medicinal. It is mainly manifested after taking antibiotics.
- Insect. Appears after bites of different insects. Especially often occurs due to bees.
- Solar. Permanent exposure to direct rays also often causes an allergic reaction.
