So the day after I turned 40 (last Weds), my wife looks at my chest and says "what is that"? Looked like some spider had chosen to attack me in the middle of the night. GRRREATTT...
So it seemed to be just kinda hanging there until yesterday, when the area around it started turning red. And I found a similar area in my armpit. And it was off to urgent care.
So now I either have an infected bug bite, or I have shingles. Yay!
