The first time i had this Charlie horse burning sensation on the left side of my head inwa9s in my 20s and driving, i had to pull over until it subsided. I have to hold my head to the left until the cramp releases. I don't have head aches. And i will go months some times before I have another cramp/Charlie horse symptom. I have told every physician, surgeon and they look at me like, what are you talking about. They have never heard such a thing.
