Welcome to Healthcare Magic
It's quite possible you have Stye
or Meibomian cysts. They usually occur because of refractive error
of the eyes. Avoid rubbing your eyes with your hands, as this makes it come more. You may need Spectacles, please confirm with the Doctor. With the antyibiotic drops the swellings should go away, if it doesn't please go bakc to the Doctor and he will advise better management.
