You thought playing with your cats was going to be good for your health? Think again! Okay, so not really. This woman, while playing with her cats, began dealing with a cervicogenic headache, where the pain comes from the back of your head - and she had to stop playing in order to get her head to stop hurting. Even after living for years with migraines, I had no idea about this kind of pain, so I absolutely recommend this this site for educating people!
