Red bumps on your back may occur with conditions related to your hair follicles. Hair follicles cover nearly every part of your body except for you lips, the palms of your hands and the soles of your feet. Red bumps on your back may also be a symptom of an underlying autoimmune disorder.
Acne may cause red bumps on your back. Acne occurs when pores on the surface of your skin get clogged. Glands in your skin may produce too much oil and lead to blockages in the pore. These blockages can rupture and cause an inflammatory reaction that produces pimples that look like red bumps on your back. Deep inflammation may cause larger bumps that are called cysts. A more severe form of acne called acne vulgaris may occur on your back and result in comedones. Comedones are small, flesh-colored white or dark bumps that give your skin a rough texture.
Infections like folliculitis occurs when hair follicles on your skin get infected by bacteria or viruses. A folliculitis infection may look like small pimples around several hair follicles. Folliculitis bumps may itch and superficial infections may clear within a few days. You can contract folliculitis on your back from exposure to bacteria in hot tubs and jacuzzis.
Autoimmune conditions and diseases such as Celiac disease may produce red bumps on your back known as dermatitis herpetiformis. Celiac disease is a digestive disorder that damages your intestine and interferes with the absorption of nutrients in your food. You are not able to tolerate the protein gluten if you have this disease. Dermatitis herpetiformis is an itchy rash that may form on your back. The rash consists of itchy bumps and blisters that persist over a long period of time.
Varicella is an infection caused by the varicella-zoster. This is a common childhood infection also known as chickenpox. A child or adult with this condition may develop hundreds of itchy, fluid-filled blisters that burst and form crust. Adult chickenpox are known as shingles. After a case of chickenpox, the virus may remain dormant in your body for the rest of your life and approximately 10 percent of adults experience a subsequent case of shingles during periods of stress.
Treatment for red bumps on your back depends on your specific condition. Consult your health care provider or dermatologist for a diagnosis and treatment recommendations for your specific condition. Acne treatment includes washing your skin with mild, non-drying and non-comedogenic soaps that do not clog your pores. Treatment for folliculitis may include topical antibiotic ointments or antipruritic ointments to help relieve the itching. The only treatment for celiac disease is a gluten-free diet. Treatment for chickenpox may include oatmeal baths and antihistamines to help reduce itching. Antiviral medications may benefit a case of chickenpox if you administer the medication within 24 hours of the first rash.
