A furuncle is a tiny boil, an infection of a hair follicle in the outer ear. It begins like a small pimple and then develops into a large local infection.
Furuncle’s can be extremely painful, any movement of the pinna or pressure on the front of the ear will make the pain intense. The person can become generally unwell as the body fights the infection. The Furuncle will develop with increasing pain until it comes to a head and bursts; often the person experiences instant relief.
Sometimes the discharge will run down the ear canal and settle in the deep canal, this can be cleared easily with microsuction.
Pain relief is the first aim, and perhaps oral antibiotics will be prescribed.
Your GP may also check your blood sugar levels as developing boils is often the first sign of diabetes.
