Generalized rash
Generalized rashes affect a large area and cover most of the body or several parts of the body. A generalized rash may be caused by an illness that affects another part of the body as well as the skin.
Common causes of a generalized rash are:
- Viruses, such as chickenpox or roseola. Viral illnesses that cause a rash are common in children.
- Common skin conditions, such as eczema or prickly heat.
- An allergic reaction to food, medicine, or other substances.
How a rash looks, how an illness develops, what other symptoms are present, and what illnesses are present in the community will help determine what treatment is needed.
How can you care for yourself when you have a rash?
Most rashes will go away without medical treatment. Home treatment can often relieve pain and itching until the rash goes away.
After a rash appears, leave it alone as much as you can.
- Use soap and water sparingly.
- Leave the rash exposed to the air when you can.
- Don't scratch the rash.
But if you have come in contact with a substance such as poison ivy, oak, or sumac, wash the area with a lot of water right away. If you can, use liquid dish soap or a mild soap and very warm running water.
If you have a rash, you should not be in contact with children or anyone who is pregnant. Most viral illnesses that cause a rash are contagious, especially if you also have a fever.
Rash: When to call
Call your doctor now or seek immediate medical care if:
- You have signs of infection, such as:
- Increased pain, swelling, warmth, or redness.
- Red streaks leading from the area.
- Pus draining from the area.
- A fever.
- You have joint pain along with the rash.
Watch closely for changes in your health, and be sure to contact your doctor if:
- Your rash is changing or getting worse. For example, call if you have pain along with the rash, the rash is spreading, or you have new blisters.
- You do not get better after 1 week.
