A rash is your body’s way of reacting to substances that it doesn’t like. Hives, eczema and dermatitis are all forms of rashes. Minor symptoms can include redness, itchiness, swelling or sensitivity. More severe symptoms can include blisters that bleed, skin that peels or turns black, and shortness of breath. If your rash is accompanied by a fever, you should contact your doctor. Because some rashes are brought on by allergies to substances, you should be very careful to monitor your condition. If you have any trouble breathing or if you are in severe pain, immediate action is necessary. Rashes commonly result from allergic reactions to medications, food, lotions, metals, plants and a variety of other substances. Changes in hormone levels can also trigger rashes. In some cases, rashes can go away by themselves, particularly if you cut off contact with the offensive material that caused the rash. Sometimes, though, rashes can be long lasting or even chronic. In some instances, you simply cannot figure out on your own what caused the rash. When these things happen, you should schedule an appointment with your dermatologist. He or she can diagnose and help treat your condition.
If you have a rash, you should try not to scratch because you may be interfering with the healing process. While many rashes may look similar to you, your doctor can properly diagnose your condition and offer specific and effective treatment options for your rash by examining the appearance and location of the condition and by analyzing your family history and symptoms. Treatments may include special moisturizers, medications and lotions.
