Having any type of rash on your abdomen can cause pain and skin irritation. Wearing articles of clothing that rub against the rash may make matters worse. Other factors, such as heat and humidity, can also cause the rash to become inflamed. Depending upon the type of rash you may have, you may require a prescription medication to alleviate the symptoms.
Your rash may have started as a small, patchy red area on your abdomen that grew larger as time progressed. The rash may have developed small, pimple-like bumps, which may itch. The bumps can begin as tiny pimples, and then begin to grow larger as the rash continues to remain on your skin. The bumps can also form deep under your skin, depending upon the type of rash and the cause.
Various ailments, such as chickenpox, an ingrown hair, a heat rash or a viral or bacterial infection, can cause you to develop a pimple-like rash on your stomach. With chickenpox, the rash can appear on your stomach, back or chest and develop small, red bumps that resemble little pimples or blisters. Later, you may experience fever, itchiness and discomfort. An ingrown hair, also known as folliculitis, may begin as a small pimple, which later develops a rash due to the irritation from the pus under the skin. A heat rash may develop pimples at the beginning signs of the rash, causing pain and discomfort. A viral or bacterial infection, such as a yeast infection or a carbuncle, can also cause a rash to appear that develops small bumps.
Depending upon the cause of the rash and pimple-like bumps, symptoms may last as few as four days or up to two weeks. Chickenpox typically lasts about four days, according to KidsHealth.org. A heat rash may remain on your skin for an extended period of time, depending upon hygiene and weather. If it's hot or humid, the rash may linger, as this provides an optimal temperature or condition for the rash to thrive in. Viral and bacterial infections may last up to two weeks, depending upon the type of infection.
Keeping your skin clean and dry can help prevent developing a heat rash or ingrown hair. An ingrown hair will develop when the hair follicle becomes clogged with dirt, bacteria and other debris. Keep away from friends or family who have chickenpox, especially if you've never had the illness, to avoid contracting it.
Before treating the pimple-like rash at home, schedule an appointment with your health care provider to determine the type and cause of the rash. Treating it with the wrong medication could worsen your condition. Avoid scratching the area, as you may spread the rash to other areas of your body. If you believe the bumps are acne-related, such as a boil, do not attempt to squeeze the site. The pus could leak onto your skin, spreading the infection to other areas of your abdomen.
