Small itchy bumps on the skin can result from a number of skin conditions and/or allergies. Problems may arise from an allergic reaction to a product or material, an insect bite, a skin disease such as scabies, or even a reaction to a drug or other medication.
Allergens can be found in many items, such as cosmetics, soaps and perfumes. Some food items can also cause an allergic reaction in people leading to red welts and itchy bumps.
Mosquito, sweat bee, yellow jackets, wasps and hornets are all known for their nasty bits and stings. Reactions to insect bites are generally mild, however some people may have strong reactions, which may necessitate medical intervention.
This condition results due to Sarcoptes scabiei, a burrowing mite with eight legs. An intense need to scratch is a common symptom of this problem, more so in the region where the mite burrows. The itching sensation increases during bed time.
Some antifungal drugs and antibiotics may cause a reaction in the body, leading to itchy bumps. Narcotics may also cause a reaction in the body that may result in similar rashes.
This condition is also called as "picker's acne." When acne is scratched and squeezed, then scars and scabs develop, which result in this condition. Oily skin, certain medications and hormonal changes are some of the common causes of acne.
