Boils are skin eruptions that are acute,painful deep eruptions involving dermis. It is commonly caused by staphylococcal infection of hair follicle with cellulitis(inflammation of cellular or adipose tissue that lies beneath the skin) and central suppuration resulting in complete destruction of hair follicle.
- Onset is sudden,location of boils is usually on the back of neck,axillae,face,buttocks,thighs,forearm.
- Pain of the affected part,sensation of heat over the affected part.
How the lesion looks
- Boils start of as small red nodule,usually apears in groups(very rarely it appears singly). Boils spread peripherally(away from the centre) and are deep seated.
- Within 3-4 days the boils becomes inflammed,with bright red appearance,conical in shape,tender.
- The skin around the boil is stretched glistering and red.
- Shedding of hair is commonly seen in boils.
- In 7-10 days the boil becomes ripe,the centre becomes yellow and ruptures with discharge of pus. Pian and tenderness diminishes.
- Spontaneous rupture and drainage with favourable prognosis.
- Shave the hairs around the boils to avoid its spread.
- As soon as pus appears it must be drained.
