Well I twisted my neck bad last week (I also have the bad habit of cracking it all the time) and I've been having bad headaches on the top right side of my head since. It also hurts when I look at lights or screens. I'm kind of a hypochondriac so don't laugh... but my friend's dad had a stroke after he went for a massage session and they cracked his neck the wrong way (it was found to be the cause of the stroke) ... am I in any danger of that? I'm not a person who gets headaches, at all, and I've been having them on and off for a week now, even after my neck is almost painless. I really feel for people with migraines now, it really sucks! it's very hard to think straight... it's very debilitating.
