anesthesia
"My pain doctor gave me 12 shots in my cervical spinal nerve roots.  He used this on me - after a couple of minutes then up to five minutes (according to him) I still was fully conscious and alert.  I told him this and I told him that I didn't think the medicine was working on me. He decided to start the injections and after the first injection (6" needle) I screamed and told him I could feel the the entire pain effects from the first shot.  The anesthetist said he would give me a second dose (did he?  I don't really know) and then we waited for a few minutes - he gave me a second shot - and I told him I was still fully alert and the medicine wasn't working."
