While your skin is the largest organ of your body, it is also the system with the least amount of protection. Your skin is susceptible to various allergic reactions, infections and injuries. Small red bumps that appear on your hands may be the result of numerous conditions that range from something a simple cream can fix to conditions that may require prescription medication.
Causes
One of the most common causes of small red bumps on your hands is folliculitis, more commonly known as an ingrown hair. According to MedlinePlus, the condition occurs when the hair follicles are damaged due to blockage, shaving or friction from clothing rubbing against it. Another potential cause is a carbuncle, which is a skin infection that causes a group of boils to gather deep below the surface of the skin. Insects biting or stinging your hands may also cause small red bumps.
Identification
The MayoClinic.com describes folliculitis as small red bumps that usually form in clusters near the follicles of your hair. They may also make the surrounding skin appear inflamed and red. The most serious forms of the condition may also appear as blisters that are filled with pus. Carbuncles cause a lump to form under the skin that ranges from pea size to the size of a golf ball. It will typically grow rapidly and appear red with a yellow center that often oozes pus. Insect bites will vary in appearance depending on the species. Most commonly, an insect bite appears as a small red bump that swells when irritated.
Effects
Folliculitis may cause the affected area to become tender and itchy. According to the MayoClinic.com, deep folliculitis begins even deeper within the skin and often causes pain. Carbuncles may cause your skin to become itchy even before it develops. You may also experience a slight fever, tiredness and nausea, states MedlinePlus. The effects of insect bites vary depending on the insect and can include itchy skin, a tingling or numbing sensation, burning and localized pain.
Prevention/Solution
To speed the healing process of a carbuncle, soak the affected area with a warm washcloth a few times daily. This helps the carbuncle drain, which is necessary for it to heal. Most insect bites can be treated with over-the-counter medications, such as hydrocortisone cream or an antihistamine. If the insect has left a stinger in your skin, be sure to remove it as soon as possible before icing down the area to prevent swelling. Folliculitis may be treated with antifungal medications or antibiotics.
Warning
While most insect bites and not particularly dangerous, an allergic reaction may be catastrophic. If you experience any type of swelling in the face, trouble breathing, chest pains or find it difficult to swallow, dial 911 immediately. You should also see your doctor if you have a carbuncle that is causing red streaks around the sore or a high fever.
