Why is my right lower eyelid swelling?

Eyelid swells: Swelling under eyelid can be due to the following [most common to least]: swelling from allergy; age issue (blepharoptosis, dermatochalasis), genetic variations; blocked meibomian gland (sty, chalazion); too much salt in diet; heart or kidney problem; mass or tumor). Consult with us to see cause & give Rx if needed. If painful, start warm compress. See eyedoc2020.Blogspot.Com for more info.
