What causes itchy rashes on skin.

Hi Thanks for your query. Itching is a normal body response to protect us from harmful external substances or parasites such as insect bites. There are many possible causes but for some people with pruritus no obvious cause can be found. Pruritus may be localised to one area or generalised over the skin. Most common cause of itching is dry skin.  It may also be caused by medicines or by internal diseases affecting the body. When pruritus occurs due to an internal disorder, we have to treat the disorder first as most of the time it will cure the itching as well. If the itching started after you started taking  particular food items then prick test can be done to find the cause of allergy. . . Avoid using any over the counter anti itch creams as they may increase your problem moisturizers if they are not suitable to your skin type.

A few general measures like avoid scratching the affecting area, applying cold compresses go a long way in reducing the itching
