What is a welt?

A welt is a raised mark on the skin caused by a blow or a skin reaction. It is typically red or pink in color and may be accompanied by itching or pain. The size of a welt can vary, ranging from small bumps to larger, more pronounced raised areas. Welts can be caused by a variety of factors, including insect bites, allergies, and physical trauma such as a strike or impact. Treatment for welts typically involves applying a cold compress, taking an antihistamine to reduce itching, and avoiding further irritation to the affected area. In some cases, welts may require medical attention if they are severe or persistent.
