So why didn't anybody mention that when you shave (except for your face, apparently) it itches like hell when it grows back?

I was recently a paid volunteer in a clinical drug trial for a new class of antibiotics some drug company was testing, and had to wear a 12-wire ECG lead setup on my chest for 2 days. In order to get a good signal they had to shave a good section of my chest. When they finally took the leads off and peeled off the circular adhesive patches it looked I had been attacked by deranged octopus that left circular red marks all over my chest and side. I use some acetone to get the rest of the adhesive off and though I was all done, but for the last week it seems that I've done nothing but scratch
