Little Red Bumps on the Fingers
Small, itchy, red bumps can be annoying anywhere you get them, but they can cause additional distress when they're on your fingers. Because you use your hands so much throughout the day, the bumps can become inflamed and irritated if not dealt with quickly. There can be a myriad of possible causes for the bumps, so see your doctor to rule out anything contagious or threatening to your health.
The most common cause for small red bumps on the fingers is allergies. If the bumps itch, and appear after you've handled something new --- such as a new soap, perfume or laundry detergent --- it's most likely due to an allergy. Taking an antihistamine and avoiding the source of your allergy should solve the problem in the future.
Oftentimes the itchy, red bumps on your fingers are just insect bites. Rub in some hydrocortisone cream on the bumps, take an antihistamine and press ice against them to relieve the itching. Red bumps on the fingers can also be a sign of scabies, which is a common skin infection where tiny mites burrow into the top layer of human skin and lay their eggs, according to KidsHealth.org. itchy bumps and lines typically show up on and between the fingers. It's transmitted through skin-to-skin contact, and you need a doctor-prescribed, medicated cream to kill the mites.
Skin Conditions and Rashes
Contact dermatitis is a common cause for small red bumps on the fingers, and it manifests very similarly to an allergic reaction. It's a skin inflammation resulting from contact with certain substances, such as soap, jewelry or makeup. You can usually relieve the symptoms with an anti-itch cream and avoidance of the offending substance. Rashes such as poison ivy or poison oak can also cause the small, red bumps.
Certain types of bacterial infections that get into the skin can also cause the small, itchy red bumps to break out on your skin. Infections can be treated with an antibacterial cream or pill; see your doctor for a prescription.
Diagnoses and Treatments
Because small red bumps on your fingers can come from a variety of sources, try a home treatment first with hydrocortisone cream and antihistamines to see if it's due to insect bites or allergies. If the symptoms don't improve, or get worse, go to your doctor. A doctor can diagnose the cause of the bumps and give you a treatment for it, usually in the form of a cream or pill.
