Skin is the largest organ of the body and is almost constantly exposed to many potential irritants. Laundry soaps, wool fibers, and insect bites can all cause our skin to feel itchy or develop a rash. More serious rashes are often caused by allergic reactions, skin diseases, or infections.
A rash is simply an outbreak of many red bumps or patches on the body. Rashes can change the appearance of skin color and texture. By looking at the body location of the rash, it is possible to determine what may have caused the rash. Widespread rashes may indicate a drug reaction, hives, or viral infection. Rashes that occur in limited locations may indicate that some type of irritant caused the rash to appear.
Skin rashes are usually not contagious and go away after some time has passed. Many over-the-counter products containing hydrocortisone can provide relief for itch and rash sufferers. Those who suffer from skin diseases such as psoriasis and eczema may need to receive treatment from physicians.
