There is very little information provided. I will start by making an assumption that it is the eye lids and surrounding area of skin that is swollen and not the eyeball. If your eyeball is swollen and painful, recommend that you go to the emergency room. Swelling around the eye is usually due to edema
(fluid) of the connective tissues around the eye. The eyelids are the most common area to develop swelling. You could have a bacterial or viral infection of your eye. If you develop pink eye
or red eyered (the color of the white part of the eyeball turns red or pink) you could also have itching, eye pain
, swelling, as well as drainage that could be yellow or green.
A sty is an infection at the base of your eyelash. The gland or the follicle
associated with the eye lash can become infected. Usually you will see a red bump that can be inside your eye lid or it can be where the eye lash exits the skin. It can be painful and cause swelling of the lids. Orbital cellulitis
is a bacterial infection that can cause tenderness, swelling, and redness if it is not treated you could develop a fever
and swollen lymph nodes. Trauma or inflammation
of the area can cause swelling. If you have visual changes
, it is very important that you get seen right away.
