Last April I had a Left Knee Revision (They took an Old Knee Replacement out and they put in a new knee). My knee healed up nicely,but everyday since May 1st I have had a headache. Turns out they are Cluster Headaches and I have found that these Nasty Headaches have interfered with my golf game. I have played only a few 18 hole rounds,but mostly 9 hole rounds.I basically play in between headaches which is no fun. My best round was on Veterans Day,I shot a 77,which was a lot of fun to do. I have a neurologist and I'm taking many meds to help cope with the headaches. I want to ask, How many of you have dealt with headaches like this and tried to play golf?
