Itchy skin, also known as pruritus, is an irritating and uncontrollable sensation that makes you want to scratch to relieve the feeling. The possible causes for itchiness range from internal illnesses, such as kidney or liver disease, to skin rashes, allergies, and dermatitis. Itchiness can be generalized (all over the body) or localized to one small region or spot.
The possible causes are numerous and varied. It may be a result of something very serious, such as kidney failure or diabetes (though uncommon), or can come from something less severe, such as dry skin or insect bites (more likely). Use skin creams and lotions that moisturize your skin and prevent dryness. Use sunscreens regularly to prevent sunburns and skin damage. 1.194 per 100,000 have been found affected by this disease.
