Diagnoses needed: What is wrong with me?

I was feeling fine but after a 14 year old scalp cyst became too large to stand I broke down and had it taken off five days ago. I had six shots all around it and half an hour of extreme tugging and pulling as she stitched up the large gap. There is a slight dip in the space now. Ten days before this I had a root canal with no crown placed until October. I awoke this morning with swollen, yellow eyelids that she had said may turn black and blue. I am not in any pain but I feel sort of dizzy and weak enough that I don’t think I should drive. I get at least nine hours of sleep but after I’m up a couple hours the weakness sets in. What is wrong with me? That pilar cyst surgery was not the “fifteen minutes” I had read about. It was half an hour . She gave me an ice pack and prescription for pain pills I haven’t needed plus extensive instructions. She was assisted by an RN. Thank you.
