Days passed. It grew.
And it itched.
It was obviously not a pimple. And maybe or maybe not a bug bite.
The red bump turned black and blue. I couldn't decide which was worse - going around with what looked like a horrific pimple or putting a Dora the Explorer band-aid on it. In the end I settled on a butterfly type bandage which then looked like I was married to a wife beater.
Over the last couple of days the itching and stinging and throbbing has spread back to my temple and straight back through my scalp. It hasn't visibly spread, but I can feel it.
