You betchya! I'll let you know. Knees are tough because you're dealing with two different types of pain, both skeletal and soft connective tissue. The big-time stuff is great on skeletal but iffy on connective tissues which are on fire. Pain sure keeps you alert though huh? Nature's pretty cool when you think about it. I find shock to be like an acid trip. It's like being outside your body and looking back in. Time stands still. Your mind drifts elsewhere and yet you see and hear everything around you.
I've even developed a resistance to anesthesia drugs. It used to be I was out in a second. Now I feel it burning and get that metalic taste in my mouth. They have to hold me down. The burning pain in the veins is just brutal. Last time they were super generous with the valium shots in pre-op. It didn't help at all. It just made the music more enjoyable. Being operated on to BB King is quite an honor. It takes about fifteen seconds for me to drop out cold now. Amazing the ways the body adapts.

I got eleven shots of Novocaine at the dentists office with little effect. They finally used gas and demerol.
