is a skin infection caused by bacteria. Cellulitis is common and can become severe. Cellulitis usually appears on the lower legs. It can also appear on the arms, face, and other areas. Cellulitis develops when bacteria enter a crack or break in your skin, such as a scratch, bite, or cut.
Common signs and symptoms:
Signs and symptoms usually appear on one side of your body. You may have any of the following:
- A fever
- A red, warm, swollen area on your skin
- Pain when the area is touched
- Red spots, bumps, or blisters that may drain pus
- Bumpy, raised skin that feels like an orange peel
Seek care immediately if:
- Your wound gets larger and more painful.
- You feel a crackling under your skin when you touch it.
- You have purple dots or bumps on your skin, or you see bleeding under your skin.
- You see red streaks coming from the infected area.
Call your doctor if:
- The red, warm, swollen area gets larger.
- Your fever or pain does not go away or gets worse.
- The area does not get smaller after 3 days of antibiotics.
- You have questions or concerns about your condition or care.
You should start to see improvement in 3 days. If your cellulitis is severe, you may need IV antibiotics in the hospital. If cellulitis is not treated, the infection can spread through your body and become life-threatening. You may need any of the following medicines:
- Antibiotics help treat the bacterial infection.
- Acetaminophen decreases pain and fever. It is available without a doctor's order. Ask how much to take and how often to take it. Follow directions. Read the labels of all other medicines you are using to see if they also contain acetaminophen, or ask your doctor or pharmacist. Acetaminophen can cause liver damage if not taken correctly. Do not use more than 4 grams (4,000 milligrams) total of acetaminophen in one day.
- NSAIDs , such as ibuprofen, help decrease swelling, pain, and fever. This medicine is available with or without a doctor's order. NSAIDs can cause stomach bleeding or kidney problems in certain people. If you take blood thinner medicine, always ask your healthcare provider if NSAIDs are safe for you. Always read the medicine label and follow directions.
- Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell him or her if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.
- Wash the area with soap and water every day. Gently pat dry. Use bandages if directed by your healthcare provider.
- Elevate the area above the level of your heart as often as you can. This will help decrease swelling and pain. Prop the area on pillows or blankets to keep it elevated comfortably.
- Place a cool, damp cloth on the area. Use clean cloths and clean water. You can do this as often as you need to. Cool, damp cloths may help decrease pain.
- Apply cream or ointment as directed. These help protect the area. Most over-the-counter products, such as petroleum jelly, are good to use. Ask your healthcare provider about specific creams or ointments you should use.
- Do not scratch bug bites or areas of injury. You increase your risk for cellulitis by scratching these areas.
- Do not share personal items, such as towels, clothing, and razors.
- Clean exercise equipment with germ-killing cleaner before and after you use it.
- Treat athlete's foot. This can help prevent the spread of a bacterial skin infection.
- Wash your hands often. Use soap and water. Wash your hands after you use the bathroom, change a child's diapers, or sneeze. Wash your hands before you prepare or eat food. Use lotion to prevent dry, cracked skin.
Follow up with your doctor within 3 days, or as directed:
He or she will check if your cellulitis is getting better. Write down your questions so you remember to ask them during your visits.
