A rash is a condition that changes the appearance of the skin. Rashes can have a variety of causes, including diseases, allergies or even emotional states. They can itch or not itch, hurt or be painless, be flat or raised, dry out, crack, weep or form blisters. No one wants to suffer from a rash. One of the first things that needs to be done is figuring out exactly which rash it is so that treatment can begin in a timely manner.
Chickenpox. Chickenpox is caused by the herpes zoster virus. The rash of chickenpox erupts from seven to 21 days after the person is exposed to it, and the person is contagious two days before the rash erupts until the blisters have crusted over. The rash can appear almost anywhere on the patient’s body, including inside their mouth. The itchy blisters appear, collapse after about a day and turn into scabs. The patient should be discouraged from scratching them because they can leave scars. Cool compresses, oatmeal baths, calamine lotion and antihistamines usually help with the itching. The symptoms of chickenpox are rather mild for children, save the itching. They usually recover within a week. Adults have more intense symptoms and take longer to recover.
