A carbuncle may heal on its own in a few weeks. But the pus within it needs to come out first. Treatment options include: Warm compress.

What is the fastest way to heal a carbuncle?

Warm compresses may promote the drainage and healing of carbuncles. Gently soak the carbuncle in warm water, or apply a clean, warm, moist washcloth for 20 minutes several times per day.

Can a carbuncle heal without draining?

Carbuncles usually must drain before they will heal. This most often occurs on its own in less than 2 weeks. Placing a warm moist cloth on the carbuncle helps it to drain, which speeds healing. Apply a clean, warm moist cloth several times each day.
