Early this morning, about a half hour left in a 45 mile ride, I experienced a bit of a tickle, then an itch on the back of my neck right at my hairline. I didn't think anything of it till I got home. I jumped in the shower and as I regulated the water flow, I noticed the palms of my hands were beginning to get slight reddish welts and were beginning to itch uncontrollably. Within minutes is spread to where I sit and the front side of where I sit, then to a lesser extent my scalp, armpits and feet. I popped two Benadryls, and jumped in the car to take my son to soccer camp about 3 hours away. During the ride, my tongue began to swell, and my upper lip ballooned to about twice it's normal size. No trouble breathing, so I kept driving trying to beat the registration deadline. Once registered and set up in his room, I asked my wife if she would drive home because I felt sleepy. 3 hours later (and two more Benadryls) I arrived home and most if not all of the swelling is gone. I have painful knee joints, and the bottom of my feet hurt whenever I put pressure on them. The hive like welts are all but gone, but I'm running a low grade fever (99.1 or 2).

Has anyone else experienced this sort of anaphalytic reaction? I have experienced bee stings, and they are full blown in much less than 30 minutes, but this one was like time release.
