A rash occurring behind the knees could happen for any number of reasons. It’s understandable to become nervous about the cause of it and worry if the symptoms are serious. A person could believe they have contracted a rare skin disease or they fear they are beginning to see the manifestation of early stages of skin cancer. In many cases, the skin rash is caused by atopic dermatitis. Other causes, some serious, will be discussed later in the article.
The causes of rashes behind the knees are wide-ranging. The first cause could be dermatitis herpetiformis. This is a rash that happens either on your back, elbows, knees, scalp or your butt. An allergic reaction to gluten is the most likely cause of this rash which may be indicative of celiac disease. Celiac disease is an allergic reaction to gluten. Other names for celiac disease are:

The common treatments for rashes like atopic eczema are medications. Creams and ointments purchased at your local pharmacy are an option. These creams have to contain steroid hydrocortisone. Some creams that contain it are: Dermarest Eczema, Cortizone-10, Cort-Aid and Neosporin Eczema. If you are dealing with mid-level eczema, a topical immunomodulator should be able to help you. These work because they modify your body’s response to allergens and stop flare ups when you come into contact with an allergen. Antibiotics and antihistamines have proven successful in stopping the itching symptoms.
Another available treatment option for you is phototherapy. Phototherapy involves doctors using ultraviolet light waves to treat people with cases of severe eczema. The two kinds of ultraviolet light used are ultraviolet A (UVA) or ultraviolet B (UVB). However, there are some health concerns associated with phototherapy. Patients treated with this method may experience, itchy skin, dry skin, freckles appearing and your skin may age at a faster rate.
Can rash behind knees be prevented?
The timeline of the rash depends on the severity of your symptoms. In many cases, an ointment will serve as sufficient treatment, but other cases require medication and if the rash is a symptom of cancer, surgery may be required to remove the cancer in your body.
How will I know if this is a common or serious rash?
This question can be best answered by your doctor. While you can do research online, this can cause you added stress if you self-diagnose and can make the rash worse. Another conclusion people tend to jump to is self-treatment. This is highly unrecommended because there are specific tests done to determine what treatment is right for you. Contact your doctor at the first sign of a rash to determine the best course of action.
