Swelling after lower eyelid surgery

I had lower bleph (transconjunctival with a skin pinch) 2-1/2 weeks ago and the swelling and drooping in my lower lids has not gone away.isaw my doctor Fri and she says it's not normal to have this much swelling and thought maybe allergies were to blame.she gave me another steroid eye drop. I haven't seen any difference.My outer corners droop. Are they always going to look like this?what other reasons could it be that I'd still be swelled in the eyelid?She said it doesn't look infected. Just red
