Erythema is redness of the skin caused by capillary problems and can be a symptom of various medical conditions. Treatment depends on the underlying cause, and it’s important to seek medical attention if there is a rapid change in skin color. High radiation exposure can also cause erythema.
Erythema is redness of the skin. It is caused by problems with the capillaries in the affected area. It can be associated with a wide variety of medical problems, including chronic and acute conditions, trauma, inflammation, infection, and some genetic conditions. It is commonly a symptom of an underlying medical problem and can be an easily spotted warning sign because most people notice the change in skin color.
Many cases of rash take the form of erythema multiforme, which is caused by allergies and some types of viral infections. Another example is erythema nodosum, in which fat cells under the skin become inflamed and red nodules develop. Toxic erythema is a version seen in some newborns, characterized by a distinctive rash that resolves on its own in most cases. Exposure to radiation, sun and infrared rays can also cause erythema.
When a patient presents with erythema, the first step is to determine what is causing the redness. If the patient feels immediate discomfort, medications may be given to address symptoms such as itching and pain. Diagnostic procedures may include blood tests, a physical exam, a patient interview, and a review of the patient’s history. Once the cause is determined, your doctor can begin providing treatments for the cause, which should resolve the red skin as well.
For example, if a patient has a rash due to a viral infection, antiviral drugs may be given to treat the infection. Conversely, if inflammation is the cause, steroids can be applied to mitigate the immune response that is causing the inflammation. There may be cases where the rash is recurring, a common problem with allergies and some autoimmune disorders, in which case the skin may discolor permanently due to damage to the underlying capillaries.
Red skin in and of itself isn’t necessarily harmful, but it can be a sign of a serious underlying medical problem. If anyone notices a rapid change in skin color, it is advisable to discuss this with a doctor. Your doctor can evaluate your situation to determine whether or not you need to take further action. It is especially important to pay attention to changes in skin color or texture for people who work in environments where there are high levels of radiation. This includes people exposed to infrared radiation, such as the heat from a laptop, which can cause a rash if the laptop is routinely used on someone’s lap.
