Just wondering if delayed razor burn was possible. The worst razor burn I have ever given myself didn't take hold until 24-36 hours AFTER I shaved. Is this common? Is it even possible? I ask because most of the razor burn threads I have noticed have concerned shaves, which had recently been completed. For instance, a number of razor burn threads seem to go something like this: "once I completed the shave my neck was killing me. When I got to work that day, people asked me what I had done to my make my neck so red, etc." These comments obviously imply that razor burn manifests itself fairly rapidly, yet I swear that I didn't realize I had razor burn until more than a day after I had shaved. Has anyone else ever experienced "delayed razor burn" or am I the only one who has ever been afflicted by this mysterious...well, affliction.
