It almost always results in a rash along a long, thin area of the body, following a nerve, and burning or stabbing pain along with itching. Skin diseases often have itching as a symptom. These include eczema , psoriasis , and seborrhea . Stings and bites , especially mosquito or gnat bites, are the most common cause of itching, mostly as a result of a mild allergic reaction to the bite. Bee and wasp stings and bites from flies other than mosquitos and gnats cause more pain than itching, but they can also cause severe allergic reactions in some people.
Sunburn can cause skin itching,especially when the burned area begins to peel or flake.
When bathing, use a mild soap or soap substitute to prevent skin irritation that causes itching. Pat yourself dry after bathing - do not rub your skin. Use a moisturizer after bathing to keep the skin from becoming too dry. Women with sensitive skin should use antiallergenic makeup and shampoo. If you think that your skin may be sensitive, check for allergies to your cologne, aftershave, etc.
