I have been suffering from cluster headaches since I was seven years old. I went into remission for three years before they returned in 2015. Doctors don't know enough about the cluster headaches to know what causes it. I do, it's passed on through family. My grandpa had them too. He was a simple man with health problems. I was unlucky my brother has no physical health conditions but he has mental illness as for me I got it all. I got a unknown neological condition on top of a rare movement disorder too. I recently found out I have been having stomach problems as well as fevers caused by the unknown neological condition. My immune system is confused because of my neurological condition. It's complicated. There's no treatment nor cure. I have tried treatments sadly nothing helps. I have to suffer through. To be honest I am use to it. I was born in pain. Hopefully I will find a doctor who will try new treatments and have some relief from these cluster headaches, someday.
