Also, make sure the mixture isn't too salty. This is the most important thing because it'll do more harm than good if there's too much salt. The idea is to get it as close to the salt content of your own body as possible, which is 0.9%, I believe.
And the stuff that's coming out of your ears probably isn't pus. If it's a white-yellowish or even clear substance, it's called lymph and it comes out of all wounds. A lot of people see it and think it = pus which means infection, but that's not the case. Infections are really rare and if you had one you'd know it; they're accompanied by lots of swelling, redness, intense pain, and dark-colored or even bright pus.
I have 1/2" lobes and 11 piercings: left helix x2, both conches, both nostrils, septum, navel, and VCH.
My lobes are small but I know a lot about stretching and how to do it safely, so message me if you have any questions!
