Suddenly for even a little bit...what would you do?

Well, last month I had such an experience. I had some testing done at a hospital and they'd put me out. All went fine, all precautions were taken and results were pretty good considering possibilities.

It was out patient, and getting home, of course I was woozy and all. Slept a lot and all that. Thing is....
The next afternoon? I realized that about 30 hours after the test, that 'SOMETHING WAS MISSING!' What was it? PN PAIN!!!!!!
Pain was down to about a 2! The buzzing, burning, gripping, dullness and all that was almost totally GONE! Could almost totally FEEL my big and little toes.
I asked myself, once I realized this - what should I do? No brainer! I simply enjoyed it immensely! I moved every part of my body that always seems to hurt and it didn't! I tried to memorize all the 'new' feelings so when/if it ended I could recall what 'normal' felt like again...[it's been over 5 years now]. This 'free' feeling only lasted about 6 aware hours, but they were WONDERFUL hours!
I am going to try and find out what anasthetics were used, I don't think I will have much luck, but there might just be something useful here for the long term.
Has anyone else ever had this experience? I sure hope I'm not alone... - j
