I aggrevate a small pimple/spot on my penis 3 days ago, so i treated it with some garlic oil and tea tree oil.
I now have a unsightly abrasion/burn in the middle right of my penis that is very noticeable. The doesn't seem to be infected and i've been apply hydrocortisone for the passed day which i think is helping.

I've had small abrasion before that healed how can i speed up the healing (cleaning/creams/oils) and how long does hydrocortisone take before it really starts to work?
would my doctor perscribe anything stronger?

Any help would be great, i'm quite worried, my girlfriend is coming to stay in 4 days and i'm not sure how to explain this.
