@lblazina Hi, and welcome to Connect from me also.
I have had two TKRs. I had general anesthesia for the first and for the second I had something that put me to sleep but it was not as heavy as general. I think they call it something like twilight sleep. If you are concerned about the spinal block you should speak to your doctor about it. I had different surgeons for my two TKRs. Prior to my second one, I told the doctor that I did not want a general again. He was fine with that.
I think they will give you some strong pain medications initially but want you to start cutting back on them rather quickly. That's what my surgeon did. I found after a week or so that I only needed the hydrocodone when I went to bed at night. I managed on Tylenol during the day. I cannot take aspirin or any NSAIDs.
