Under the eyelid skinfold uncomfortable bump like growth...does anyone know what this could be?

Without seeing it...: ...I would suggest the possibility of a stye; however, it is impossible for any physician to give you a certain diagnosis without examining the area of concern. If it has only been present for a couple of days, try warm compresses and see your physician if it persists. If it has been present for longer, please take care of yourself and have it evaluated.
