I stumbled upon your web page by accident. I have lived the last 30 years with profound migraine and trigeminal neuralgia. I am on some powerful meds and am trying to put off MVD (microvascular decompression) surgery. My headaches are chronic and have absolutely stolen the best years of my life. I have almost learned to expect and just deal with the incessant pain. But I think I just may have accidentally made an odd discovery. I wanted to lose a few pounds and I decided to do Dr. Atkins Fat Fast for a few days - which is simply cream cheese and nothing else. Within two days my head was pain free. So I am thinking this is very strange: is eating food giving me headaches???  I began to research and came upon histamines. I am amazed as I have never been ‘allergic’ to anything and never had sinus problems. I did note to the doctor that I was certain oranges had triggered migraine attacks - and wine or alcohol and dark chocolate. He told me to stay away from them but never mentioned histamines. I used to have friends … a life ... I have contemplated suicide many times. I have been told to put ice packs on my head. I fantasize about somehow being present at my own autopsy and taking a hammer and beating my own head and face to pieces. Now I think I am on to what might have caused this pain all these years.  – by email, USA [preservative-free cream cheese is one of many failsafe foods - S]
