Can a sty subside by itself?

Whether a sty can subside by itself depends on many factors. The patient's own recovery constitution, as well as the virulence of the bacteria, and the inflammatory reaction of the entire eyelid are related. Some sty can subside by itself after some medicine or smearing medicine. Some sty will reach the suppurative stage after medication, requiring incision and drainage in the hospital. There are also styes that, even after the suppurative stage, still form scar granulation in the body, which may require surgery to remove.
