Talk to a doctor or dermatologist if the itchy bumps on the skin last longer than two weeks, the Mayo Clinic suggests. Bumps that respond to self care do not necessarily require medical attention. Bumps that distract from your normal daily routine or that prevent you from sleeping need to receive treatment from a specialist. Other symptoms of more serious conditions include fatigue, weight loss, changes in urine or bowel movements, fever and skin redness.
WebMD states that hives are a common cause of itchy skin bumps. They are a reaction to allergens in the body. Most hives go away on their own without treatment, but persistent or severe outbreaks of hives, especially near air passages, require medical attention.
Pregnancy causes itchy bumps on the skin, especially around the abdomen and thighs, explains the Mayo Clinic. Skin conditions such as eczema, scabies and lice cause these symptoms, but are usually accompanied by red, irritated skin or blisters. Bumps that itch without redness usually result from dry skin due to weather changes or washing the skin too often.Learn more about Pain & Symptoms
