Watery bumps on the skin can be caused by a variety of factors. Various skin conditions can cause such symptoms, as can skin irritation, allergies, viral infections or bacterial infections. Successful treatment of watery bumps on the skin depends upon finding the source of them, which may require the assistance of your family doctor or dermatologist.
Causes
Contact dermatitis is a common cause of watery bumps on the skin. This condition is caused by direct skin contact with an irritant or allergen, such as detergents, skin care products, costume jewelry and poison ivy or oak. Heat rash can appear as small, fluid-filled bumps, as can a chronic skin condition called dermatitis herpetiformis, which is frequently linked to gluten sensitivity, according to Medline Plus. Dyshidrosis, according to MayoClinic.com, is a condition in which small, fluid-filled bumps appear on the palms and fingers of the hands or the soles and toes of the feet, and is often associated with allergic conditions. Viral infections that can cause such symptoms include chicken pox, shingles and hand, foot and mouth disease. Impetigo is a bacterial infection that can produce blisters on the skin.
Symptoms
Contact dermatitis can produce redness, irritation and blisters in areas of skin that have made direct contact with and allergen or irritant. Heat rash often occurs in areas of friction, such as around waistbands or in the diaper area during hot, humid weather. Dermatitis herpetiformis usually appears as bumps or blisters on the elbows, knees, back and buttocks. Dyshidrosis produces itchy blisters on the hands and feet that can be accompanied by cracks or fissures on the fingers or toes. Viral infections that cause skin blisters are generally accompanied by fever and fatigue. Impetigo can cause blisters on the face and body that burst easily to cause crusty sores.
Treatments
Treatment for contact dermatitis depends upon locating the source of irritation and limiting exposure. Heat rash can be resolved by cooling the area with cold compresses. Antibiotics are often used to treat dermatitis herpetiformis and a gluten-free diet is often recommended. Treatments for dyshidrosis include antihistamines for the itching, a variety of prescription strength topical creams and phototherapy. Viral infections and impetigo will generally clear on their own within a few days.
Considerations
Scratching or popping watery bumps on the skin can lead to scarring and infection. In the case of viral or bacterial infections, scratching, rubbing or popping blisters can spread the rash to other parts of the body. Untreated dermatitis herpetiformis can, according to Medline Plus, significantly increase the risk of developing intestinal cancer.
Warnings
Seek medical treatment for watery bumps on the skin that come with a high fever or persist for more than a week. If swelling is present, the affected area feels hot to the touch or begins to ooze pus or fluid, these symptoms could be an indication of infection and should be evaluated by a medical professional.
