If you have an itchy skin rash, it can be quite an uncomfortable experience. There are many different types of rashes which can be itchy. However, not all of them are the same and not all of them are treated alike. Sometimes, you may experience itchy skin with no rash. At other times, you may develop a non-itchy skin rash. For a formal diagnosis it is best to visit a dermatologist and get an opinion. Here are some of the common itchy skin rashes that you may have. Psoriasis This is a skin condition which is almost always chronic in nature. This is an autoimmune disorder in which the immune system attacks healthy, normal skin and causes thick and heavy rashes. The rashes are scaly and may appear irritated and red. They also have a distinct border and are usually found around the scalp, knees and elbows. Pityriasis Rosea This is another kind of itchy skin rash which has a very distinct and striking appearance. This rash starts up with a single round lesion which is first observed on the trunk of the person. The rash then spreads slowly. This is one of the rashes that causes a lot of itching and lasts for about 6 to 8 weeks. Poison Ivy
Poison ivy allergies can cause itchy rashes which may crust and ooze. These rashes are caused when the skin comes in contact with the poison ivy plant, which contains a chemical known as urushiol. This rash starts building as a blister. There may be redness on the skin that slowly spreads. As the redness spreads, blisters begin to form on the skin. These are usually treated with topical steroids. Chicken Pox Chicken pox is a viral disorder in which rashes begin to appear all over the body. This is a highly contagious skin condition. Though this condition is not considered very dangerous, it can turn complicated if a pregnant woman develops chicken pox. Those who are exposed to the virus are also at an increased risk for developing shingles later in their life. Scabies Scabies is a rash which is caused by a tiny burrowing mite. The mite feeds on human tissue and blood, and can cause small bumps all over the skin. The rash may turn red and is often seen located on the wrists, armpits, between fingers and around the waist. The rashes are extremely itchy. They can be treated with a medicated lotion. However, the rashes remain on the skin even after the mites have been killed off. Skin Rash Causes There is no exact meaning to the term 'rash' when used in relation to a skin condition. A rash may signify an abnormal skin condition or an outbreak of bumps on the skin. There is an alteration of the way the skin appears and feels. Skin rashes may be localized in specific areas of the body or could even be widespread, with similar symptoms occurring on various different parts of the body. Depending on the usage of the term 'rash' there are three main categories into which all rashes could be classified. These categories have been specifically devised to aid the doctors in diagnosing and treating these skin conditions. The types of skin rashes are Dry and scaly patches of skin which are not caused by any infection. Dry and scaly patches on the skin which are caused by infections or allergies. Bumps which are itchy and may begin to ooze, anywhere on the body. Rashes are not always dangerous; however, if they are itchy, they can bleed on repeated scratching and cause infection. Since there are different types of skin rashes, it is always advisable to take a doctor's opinion instead of self diagnosing the skin rash. Proper evaluation of a rash would help the doctor diagnose it correctly and treat it accordingly. Usually, scaly and dry patches do not cause infection. They are generally referred to as a skin condition known as eczema. However, itchy skin rashes may not be as harmless. If they itch a lot and are scratched repeatedly, you may end up breaking the skin and exposing the rash to bacteria and viruses. This should not be taken lightly and should be shown to a doctor as soon as possible. Depending on the type of skin rash you have, the doctor will be able to treat it. A lot of skin rashes occur due to allergies. Allergic reactions to proteins, resins, pollen, bee stings, poison ivy and other chemicals may cause the skin to break out in rashes. The treatment of the allergic condition usually takes care of the rashes as well, which are nothing but symptoms of the allergy. Other rashes, which may be due to genetic disorders, would require extensive testing and probing, before a treatment may be recommended. Such rashes include atopic dermatitis, a condition where there is hereditary eczema. Rashes caused by bacterial or fungal infections are usually taken care of by topical antibiotics or antifungal ointments.
