What is dermatitis?
Dermatitis, or a rash, is an area of swollen skin. If you are at early stages of dermatitis, or your dermatitis is mild, you may experience itchiness, dryness, and redness. More severe dermatitis can show up cracks, pain, blisters, and raw patches of skin.
Some rashes develop right after you have the problem. Some others appear after several days. Some rashes can clear up quickly. Some others can stay on your skin for a long period of time.
Several things can cause your dermatitis and your doctor will design proper treatment for you based on the specific type of condition. Thus, it is important to determine what kind you have before you have it treated, although treatment may be similar for most kinds.
