What is nettle?
Nettle rash is a condition that is caused by the problem of the immune system and usually not from exposing the cops. The rash appears on the skin like red areas that can be raised in the skin. Although the condition can be resolved during the day, it tends to return and return to the affected person. Possible causes include allergies to food, reactions to medicine and exposure to animals.
In a healthy person, the immune system protects the body from danger, such as infectious disease. Sometimes inflammation, redness and swelling that the immune system can use as tools against infection is randomly induced in response to substances that should not pose any significant danger to the body. This occurs in cases of nettle rash, but often one cannot find out what substances or conditions cause a rash.
Usually the nettle rash produces raised hives on the skin that is red and itchy. This condition is also called drilling or hives, and may be present in chronic form that regularlyIt affects people or acute form, rarely. Although the placement of stains on the skin may change over time, a typical case of nettle rash disappears after one day.
swelling and inflammatory redness are caused by the presence of a substance called histamine in the affected area. Histamine levels grow with an allergic immune response and signal on blood vessels near the assumed attacker to escape the liquid into the skin, thereby increased bumps associated with the condition. Since histamine is an integral part of nettle development, antihistamine drug may be beneficial for the affected person.
When a person is able to find out what the cause of nettle rash is, it can be a natural, artificial or physical cause. Natural triggers include pollen, insect bite and food. Artificial causes include drugs such as antibiotics and anti -inflammatory anti -inflammatoryness. Folders in the exposure of perfume or nicLU can also create a characteristic rash. Even changes in the physical environment can produce nettle rash, such as sun exposure, physical pressure on the skin or changes in body temperature.
If one experiences many episodes of rash, you may also have a problem with the immune system, but this is not common. Some cases of nettle rashes, characterized by a rash around the mouth, on the hands and next to the eyes, are caused by a condition called hereditary angioneurotic edema. This is due to genetic mutations and requires the advice of a doctor rather than antihistamine treatment.
