When you have a rash, it can be embarrassing. At the very least, it can be uncomfortable. A rash is technically a type of inflammation that can change the color or texture of your skin.

This can concern you even more because you are unsure about what could have caused it.
What Causes a Non-Itchy Rash?
Normally, a rash happens because of an allergy. You may be allergic to a type of food, chemical or your clothing. Some people are also allergic to certain types of laundry detergents. By finding out the cause of the non-itchy rash, you can figure out ways to prevent it from happening and treat it.

One common cause of a non-itchy rash is from heat. Miliaria crystalline is what makes up a heat rash. These look like small bumps on your skin that are clear-white and filled with fluid. They can burst open and release the extra fluid. While this condition is more common in babies and children, it can occasionally happen in adults as well. There is also a heat rash known as miliaria profunda. This type of heat rash happens in adults who have engaged in a lot of physical activity. It makes large bumps that look like the color of your skin and form deep beneath the skin’s surface. If this is the cause, you may notice dizziness or nausea because of the lack of sweat.
When you have this type of rash, your best treatment option is to prevent it from happening. Avoid sun exposure and wear lose clothing. You do not want to use fragrant soaps that dry the skin. Thick lotions could also clog your pores. If you experience symptoms like nausea, a fever or the chills at the same time, then make sure to go to the doctor right away.
2. A Drug Rash
When you are exposed to certain drugs, it can cause a rash. These drugs could be antibiotics, diuretics or anti-seizure medication. Your non-itchy rash could be due to an allergic reaction or side effects of the medication. This type of rash will generally start within the first few days of the medication and will look like a bunch of red spots. Over time, these spots start to spread to the rest of your body.

If you are having an allergic reaction that causes breathing problems, get medical attention immediately.
3. Irritant Contact Dermatitis
Your skin may occasionally come in contact with something that irritates this. One of the most common causes is the type of laundry detergent or cleaning product that you use. If you do come in contact with some type of chemical irritant, you can develop a non-itchy, dry rash. The areas on your body with the thinnest skin like your neck and eyelids are most sensitive to these irritations. The severity of your rash will also depend on how long you were in contact with the irritant, the type of irritation and the amount.
Your first goal is to wash the affected area completely so that the irritant is remove. Afterward, make sure that you avoid the irritant in the future.
4. Pityriasis Rosea
This condition is also known as Christmas tree rash. It tends to develop in a large, circular patch on your chest, stomach or back. It will first start as a herald spot about 4 inches wide. Afterward, it starts to spread in small patches to nearby areas. It is called a Christmas tree rash because the small patches look like the branches of a Christmas tree. This rash is most common in teenagers and people ages 20 to 35. While it can itch, it can also be non-itchy.
Most cases of Christmas tree rash tend to heal on their own in about 6 to 10 weeks. If it is itchy or bothering you, your doctor may be able to give you antihistamines or medicated lotions to help.
Intertrigo is a rash that starts because of skin friction. The friction causes inflammation, and it tends to occur on areas of your body that are exceptionally warm or moist. This makes it common in spots like your armpits, under your breasts, in abdominal skin folds, between your toes or around your groin. This rash can be extremely painful and sensitive. If it becomes severe, it can cause cracks in your skin, sores and bleeding. While it is normally not itchy, intertrigo can sometimes itch.
If you have this, try to keep the affected area as dry as possible. Keep it clean and work to reduce the inflammation. A powder may be able to help with the inflammation and stick to loose-fitting clothes. Being overweight makes intertrigo more likely, so you may want to lose weight to prevent it from happening again in the future.
