I have noticed recently that my jawline and occasionally part of my neck start to itch several hours after I shave. It's usually in the neighborhood of at least 8-12 hours after the shave and also seems exacerbated by having slept. If I look at my jawline closely I can see a few small ingrowns (or what looks like could become ingrowns) here and there but I don't think it's enough to cause this widespread itch. Occasionally it will happen anywhere i've shaved too, sideburns and cheeks, etc.
I think it might be more of a razor rash of some kind. I know we have discussed this before around here by search proved fruitless. Anyone know what to do to clear this up?
