Bumps on the skin are caused by a variety of conditions, including contact dermatitis, psoriasis and fungal infections. These bumps, however, can be uncomfortable and embarrassing. Learning the underlying cause assists in choosing the right treatment method. It's also important to know when to contact a doctor about skin bumps.
Causes
Contact dermatitis is caused by the skin's contact with irritants, such as detergents, soaps, clothing or metals. Psoriasis, another common cause of bumpy skin, is caused by an immune system problem. In psoriasis, the body's T cells attack healthy cells by accident.
Ringworm, a type of fungal infection, is caused by mold-like fungi that lives on the outer layers of skin. This infection is very contagious and is spread by humans and animals, or by coming in contact with infected objects.
Treatments
Contact dermatitis is treated by applying over-the-counter hydrocortisone creams. Applying a wet dressing over the bumps allows the medicine to soak in more effectively, notes MayoClinic.com. Oral antihistamines, also available over-the-counter, are used to minimize irritation associated with bumps on the skin.
Treatment for psoriasis includes the use of topical corticosteroids or a prescription topical vitamin D analoque cream to slow skin cell growth. Prescription topical retinoids, such as tazarotene, are also prescribed for this skin problem.
Fungal infections are first treated with nonprescription lotions containing the ingredients clotrimazole or tolnaftate. If the infection doesn't respond, prescription lotions, such as butenafine or ciclopirox are used. Oral prescription medications, such as griseofulvin or itraconazole also treat fungal infections.
Considerations
Apply an unscented and dye-free moisturizer daily if you struggle with contact dermatitis. Moisturizers provide a barrier between you and the irritant, minimizing the chance of skin outbreaks, according to MayoClinic.com. The best time to apply a moisturizer is within three minutes of getting out of the bath or shower.
Prevention
Prevent contact dermatitis by avoiding the irritating substance. An allergy specialist can assist with identifying the allergen. Rinse the skin thoroughly with warm water if you come in contact with the substance to avoid developing bumpy skin.
Alternative treatments, such as omega-3 fatty acid supplements may ease psoriasis, according to MayoClinic.com. Prevent fungal infections by washing your hands often to prevent catching the infection. Wear shoes at public places, such as pools, and avoid sharing personal items, such as socks or towels.
Warnings
If bumps persist for two weeks or longer without improvement, contact your doctor so he can examine the bumps and diagnose the underlying cause. Your doctor can also prescribe medications that can clear up any existing infection and prevent new bumps from forming.
