Distinguishing Different Types Of Skin Rashes

Everyone, at one time or another, breaks out with some kind of rash. Rashes can be caused by many different kinds of things and many of them are very distinguishing. Read on to find out the most common, and how to identify and treat them.

The skin, like our cardiovascular or gastrointestinal, is a body system. It is known as the integumentary system and it is your body's first line of defense against disease. It is the body's largest organ and it serves this function of defense. The skin also controls the temperature of the body. The skin is made up of three layers, the top layer, the epidermis, the middle layer, the dermis and the bottom layer is called subcutaneous tissue. There are many things that can occur on the skin, one of which is a rash.

Everyone, at one time or another breaks out with some kind of rash. Rashes can be caused by many different kinds of things and many of them are very distinguishing. A rash can be defined as any spots or red markings that appear on the skin, which is often itchy. There are many different types of skin rashes. People develop rashes for different reasons, but usually it is due to an allergic reaction to something, either by direct contact or by ingesting something that the person in allergic to. Also rashes can be symptoms of certain diseases, such as chicken pox, measles or scarletina.

One such is known as dermatitis. Dermatitis is a form of skin inflammation or swelling. Symptoms of dermatitis include redness and inflammation of the skin, usually localized. The red area may form tiny blisters that leak clear fluid, and then become crusty. There is also severe itching. This is probably the worst part about a rash. There are actually many different kinds of dermatitis. Exposure to poison ivy, poison oak or poison sumac is an example of contact dermatitis because a rash due to an allergic reaction develops as a result of direct contact to the skin. Other common causes of contact dermatitis include allergic reaction to wearing certain jewelry such as nickel, wearing certain perfumes, using certain makeups, shampoos, detergents for your clothes, household cleaners or solvents,etc. It is important for you to know what you are allergic to and best dealt with by avoiding the things that you are allergic to. Sometimes someone doesn't know they are allergic to something until they develop the rash, and stumble upon it by accident. It can take up to a day or two to develop the rash, so remember what you have been exposed to. Contact dermatitis can usually be treated at home with antihistamines, such as benadryl, orally and topically, such as hydrocortisone creams. Use as directed. If it gets worse or doesn't' clear up, see your doctor.

Atopic dermatitis is a general rash that is caused by ingesting certain foods, such as, eggs, fish, peanuts, seafood, or milk. If you think a rash is caused by a certain food, try taking it out of the diet until the rash is cleared then slowly reintroduce it. If the rash develops again, chances are, it is a food allergy.

Other things that can cause a rash are medications. If rash develops after taking a certain medicine, such as a prescribed antibiotic, contact your doctor as soon as possible. Allergies to insect stings can also cause rashes and swelling. Once you have an allergic reaction to an insect sting, such as a hornet, it is possible to become even more sensitive to the sting, making the next sting you get even worse to where it could cause more swelling, even generalized swelling and possibly breathing difficulty. Talk to your doctor about wearing a medical alert bracelet and possibly the need for premeasured syringes of epinephrine that can be self-injected for emergencies.

Treatment of most rashes can be done at home. Often a person goes to the doctor with an unidentifiable rash and the doctor may prescribe mild steroidal treatment, such as prednisone. The most important thing is not to scratch, as hard as that may be. Also keeping the skin slightly moisturized with a mild hypoallergenic moisturizer, that is fragrance and odor free. Avoid hot showers and baths, as this tends to aggrivate the rash and make it itch more. Use mild soaps and nonabrasive sponges. Avoid scratchy or itchy or overly warm clothing. Dress cool and light in breathable fabrics like cotton.

Complications can occur with rashes, such as a mosquito bite being scratched and bacteria can invade it, causing imetigo, also known in layman's terms as indian fire. If blisters or pus forms, the rash gets worse instead of better, or if fever develops, see your doctor. There is probably a secondary bacterial infection such as staph, and you may require antibiotic treatment.
