Bulge Directly Under Eyelids After Lower Bleph. Residual Swelling?

The "roll" just underneath the incision site is swelling within the orbicularis muscle [which is responsible for eyelid closure] which will resolve over time. The swelling further down on the eyelid, as it transitions to the cheek, dubbed festoons, develops as the fluid/bruising settles due to gravity,.  Often this swelling is the last to resolve, sometimes taking weeks. In younger patients such as yourself the resolution is usually quicker.

You are early in your recover, so no need for be too anxious.

Best of luck

Certainly, swelling associated with bruising is still acute.  It changes daily and really changes in the hours between when you go to bed and wake up.  Start every day with cold compresses.  Watch the salt intake.  Make time for cool or lukewarm compresses during the day.  That will boost your recover speed.

It can take several weeks to even a month or two to see all the intial swelling from eyelid surgery resolve completely.  As long as your eyelid function is good, that you are able to open and close your eyelids,  protect your eyes from drying, and that you are having no visual difficulties, be patient.  Discuss your concerns with your surgeon and you will see continued improvement with time.
