I don't know if it is or not, but my sister used to get them when she wore contacts. She wasn't getting the contacts cleaned properly. She would get a lump in her eyelid. On the inside of the lid, it would look like a yellow knot. Her eye would become all red and bloodshot looking. She said it was very painful. She went to the doctor, who prescribed her an eye ointment to place inside the lower eyelid. It worked, whatever it was! I pray it gets better for her.
