How are carbuncles diagnosed?
Your doctor can usually diagnose a carbuncle by looking at your skin. A pus sample may also be taken for lab analysis.
It’s important to keep track of how long you’ve had the carbuncle. Tell your doctor if it’s lasted longer than two weeks. You should also mention if you’ve had the same symptoms before.
If you keep developing carbuncles, it may be a sign of other health issues, such as diabetes. Your doctor may want to run urine or blood tests to check your overall health.
How are carbuncles treated?
The following medical treatments can be used for a carbuncle:
- Antibiotics are sometimes needed for treatment. They’re either taken orally or rubbed on your skin.
- Pain relievers can be used if necessary. Normally over-the-counter medications are enough.
- Antibacterial soaps may be suggested as part of your daily regimen.
- Surgeries may be used to address some deep or large carbuncles. A carbuncle may be drained with a scalpel or needle.
You should never try to drain a carbuncle yourself. There’s a risk that you’ll spread the infection. You could also end up infecting your bloodstream.
