If your vision is good, I presume there is no internal wound. Had you had anything on the inner side of your lid that would scratch your cornea
and affect your vision. But if it's hurting as bad as you are describing with lid swelling, it's of concern.
Is your eye remaining red? Do you have intolerance to light? are you using any drops now? Did you have any oral antibiotics
or pain killers? The swelling is only in left?
Do try Refresh liquigel. It will atleast give you a soothing affect.
