Welcome to HealthcareMagic
Now you must do daily dressing with antiseptic povidone iodine
solution, make sure clean all puss, fluids, blood, etc.. then you can apply triple antibiotic
, neomycin, polymyin) and sterile gauze fixed with microporum tape. Continue oral antibiotics
,anti-inflammatory medication( ibuprofen, naproxen, etc..) and in such conditions your swelling can subside within maximum 7-10 days.
I wish you good luck and speedy recovery.
