anesthesia
"I am 66 years old and have had a number of colonoscopies.  The anesthesiologist has never used Propofol on me before.  This was the 1st time that I have ever been totally knocked for the procedure.  My colonoscopy was last Monday, 9/11/17.  I have had one day since then that I felt normal.  My 1st reaction was arriving home totally out of this world and after making it to the bed, sleeping for the next 12 house with my clothes on.  When I woke up I had a severe headache across my face.  Needless to say I did not go back to work until Wednesday.  Wednesday, I felt normal until the end of the day when the headache emerged now in the crown of my head.  Thursday and Friday, the headaches have continued. However, I am pretty much normal now."
