What is a stye?
A stye is an infection in the root of an eyelash. This swells and fills with pus and develops into a small red lump on the edge of an eyelid. The eyelid becomes sore. The infection may spread along the eyelid and the whole lid may become red and inflamed. There may be a small spot of yellow pus where the affected eyelash comes out of the eyelid.
What causes styes?
A stye usually occurs for no apparent reason. The usual bacterium (germ) that causes the infection is the staphylococcus. This is a common bacterium that is often found on healthy skin. It usually does no harm, but sometimes it invades the skin to cause infections such as boils, abscesses, styes, etc.
What is the treatment for a stye?
Will it happen again?
Most styes are one-off events. However, some people seem prone to getting them. At the first sign of a stye, try hot compresses as described above. This may 'nip it in the bud'.
