Skin growths can occur anywhere on your body for any number of reasons. A growth of any kind underneath your eye can be troubling, depending how close to the eye it is. Reasons for a growth to appear under your eye could include a sty, a skin tag, cyst, allergic reaction or something more serious, such as skin cancer. Caring for a growth will depend largely on what the growth is and how it may affect your overall health. Consult your physician if you feel the growth may be more than just a superficial mark.
Inspect the growth to help determine your course of action. Contact your doctor if you are in pain or if you see any pus or discharge.
Look to see if it is on your eyelid, in which case it is likely a sty. A sty resembles a pimple and may cause pain and swelling, or rub against your eyeball when you blink.
Place a hot, moist cloth over the your eye for 10 or 15 minutes, several times per day if you have determined the growth is a sty, says the All About Vision website.
Clean the area of the growth regularly and watch for changes, says Medline Plus. Contact your doctor if it continues to grow or doesn't show signs of leaving after a week or two.
Contact your doctor if the growth is a skin tag and you want it removed. Skin tags are harmless, hanging pieces of skin that some people want removed for cosmetic reasons.
