can you get surgery with active discharge / infection?

my surgery is due in a week and i’ve been having some discharge and some pain in my cholesteatoma side ear. i’ve been doing antibiotic drops for a week and it’s still tender - my primary care wasn’t sure if it’s an infection or the cholesteatoma causing discharge and irritation.

has anyone had surgery whilst actively ‘gooping’ out from their ear? i’m really worried i won’t be able to go ahead with it because work have arranged so much cover for me (i’m a lecturer) and i just really want to surgery over and done with :(
