Furuncle on Tummy Pictures - 4 Photos & Images
Boils (furuncles) can develop anywhere on your skin, but they're most likely to occur at the site of an infected hair follicle (a hole a hair grows out of).
Boils most commonly develop on areas of skin where there's a combination of hair, sweat and friction, such as the neck, face or thighs. Over time, pus forms inside the boil, causing it to grow larger and become more painful. In most cases, a boil will eventually burst and the pus will drain away without leaving a scar. This can take from two days to three weeks to happen. Boils are more common in teenagers and young adults, especially in males. Young males living in overcrowded and possibly unhygienic conditions are particularly at risk.
