Countless types of skin conditions exist, and there are just as many ways to contract them. You may be suffering from internal causes, irritations from external materials or a fungus contracted from a public bathroom. These come in many shapes and sizes, but if you develop red, circular blotches on your skin, it can be a little easier to identify the cause.
The most common cause for blotchy skin is a fungal infection, particularly if the marks are distinctly ovular. Fungal infections are not overly serious, though they can be uncomfortable and require special treatments. In less common cases, you may be dealing with a rash called erythema multiforme, which can result from several different causes.
Erythema multiforme usually develops in conjunction with strep throat or another viral infection, and it sometimes occurs in response to certain medications. If you develop these blotches on the skin, this can be easily identified by evaluating your recent history for any of these precursors. These can also have a target-shaped look to them, according to FamilyDoctor.com. If you have a fungal infection, you may experience itching at the location, or you could suffer from some slight pain.
In the case of a fungal infection, you should wash the skin periodically, maintaining good hygiene, and apply an antifungal medication to the skin. This can be an over-the-counter medication or, if needed, you can get a prescription medication from your doctor. Erythema multiforme is a more complex condition, so seek out medical attention from a doctor if you have this.
You are much more likely to develop a skin condition or have an existing condition exacerbated if you have diabetes. According to the American Diabetes Association, having diabetes will lead to or worsen a skin condition at some point in the lives of 33 percent of individuals suffering from the disease. Diabetes patients are much more susceptible to skin conditions as well as many other bodily problems, and in some cases certain skin conditions happen almost entirely to individuals with diabetes.
If you are unsure of the cause of your skin condition, seek medical help. While it is unlikely, there are many rare types of skin conditions that are difficult to diagnose at home and require a doctor's attention. Additionally, some of these can be life-threatening and may need immediate medical attention.
