Never used antibiotics once for this treatment and I have done it several times.
Antibiotics takes way too long and doesn't always work depending on the size.
Once you remove the gunk your body will process any excess which is left very quickly as its minimal.
Soon as you drain it, it's reduced almost back to normal, the next day you can't even tell it was there.
And one time I left it almost a week before I did the drain and it was a huge lump on my chest. The size of two golf balls side by side.
My gf at the time almost vomited from the amount that came out lol.
Bro I respect your guts ... you got steel ba**s ... broly but I agree with R14 you should at least do 3 days of amoxicillin 500mgs day to be safe after abscess draining ...
