A stye usually heals in 5-7 days. To relieve the pain, apply a warm compress to the area for 10-15 minutes, 4 times a day, and take mild pain relievers. Microwaving a potato and wrapping it in a cloth will provide a longer term warm compress. If the bump grows or doesn’t go away, see your doctor. If the redness spreads or swells quickly, or if you develop fever, seek medical attention promptly.
