would orajel numb my forward helix / ear?
The orajel will numb your ear if you apply it. This is because it contains benzocaine component which enters into the bloodstream and can be life -threatening. Visit http://www.livestrong.com/article/130223-orajel-side-effects/ for more details.
probably just the outside as it does with the mouth, good luck(:
You dont need to be trying to pierce yourself .
