Skin rashes may appear as red patches or scaly patches. It may or may not itch, depending upon the cause of their occurrence. They may remain localized in one area or may spread on the whole body.

Skin Rashes That Need To Be Taken Seriously

Self diagnosis is not appropriate. The dermatologist must be visited as soon as you discover that the rash is taking more than a week to heal. There are certain characteristics which will help in making out the difference between a normal rash and a dangerous one. The abnormal rashes will be affecting both the skin and the nearby mucous membranes.

Example, in women the rashes may appear both near the vagina and on the mucous membrane of the urethra. Likewise, they may appear on mouth and inside the lining of the lips and nostrils. Rashes with blisters extend on scratching. Serious rashes appear painful when they burst open. They will be carrying some moist substance suggesting some type of infection. Normal rashes may itch but they do not have blisters on top of them.
