SEVERE reaction to anesthesia following my knee surgery in August 2021.  I went 11 days unable to sleep to the point I believed my dreams were reality. I also began stuttering and slurring my speech. My vocabulary and spelling were impaired. My memory was severely impaired. I had involuntary jerking. Until I finally fell asleep and got trapped in a nightmare that caused me to nearly injure my mom, but my loved ones nor the paramedics could get me to regain consciousness until pulling into the hospital at which time my speech was so impaired I could only ask the paramedic the word “mom?” The ER dr prescribed meds to reset my sleep cycle which helped a lot but I still severely struggle with my memory and sometimes with my vocabulary. I think the damage of this reaction will forever affect my memory. I however have been under anesthesia since with absolutely no problems. I believe that particular anesthesiologist used a different drug than I had ever been given before that created the reaction  I experienced.
