I cured mine with 10vol.% lavender oil + 10vol.% thyme oil in carrier oil (grapeseed oil). I couldn't be bothered by going to a doctor and it worked fine. Essential oils are non-selectively toxic so do be careful.
Do you live in the USA?
I can't believe "going to the doctor" can still be a problem, unless you're in war zone or one of the worlds' poorest countries but that doesn't apply to the US, does it?
