Well, it doesnt itch at all on the penis or near the elbow, but i have had the bump on my penis for quite some time now, so that is what really worries me.
Hi,
Bumps that blanch( i.e. turn white) on pressure applied are usually hives, an allergic reaction.Hives are red, itchy welts or swellings on the skin that often come in clusters. In doctor speak, hives are known as "urticaria."
When an irritant comes into contact with your body, your immune system sends chemicals, including histamine, to fight it. The sudden spike in histamine levels can cause an outbreak of hives in the upper layers of the skin. Hives are often caused by a hypersensitivity to:
•Foods (commonly eggs, shellfish, nuts, berries, dyes, or other additives)
•Drugs (any drug can touch off an allergic reaction, although allergies to penicillin, sulfa, and aspirin are especially common)
•Pollens and plants (nettles, poison ivy, poison oak, and so on)
•Animal fur
•Insect bites or stings
•Exposure to heat, cold, or sunshine .
Other potential triggers include physical exertion or exercise, stress, illness, chemicals, cosmetics, textiles, and pressure from materials rubbing against the skin.
Comfort is the main goal of treatment, since most hive outbreaks are relatively minor and short-lived. To soothe itchy skin, try cold compresses, calamine lotion, a cool shower, or a tepid bath with a few tablespoons of cornstarch (the kind sold in drugstores) thrown in.
Try an over-the-counter antihistamine to reduce your body's response to the irritant and to relieve pain.
