How To Treat Chronic Migraines And Hemicrania Continua?

Hi there. I was just reading about CSF leaks. I have been quite sick this year with a variety of symptoms -- chronic migraines, significant eye pain (usually in my left eye), fatigue, nausea, etc. One of the symptoms I noticed also was a runny nose from one nostril (my right). I have seen 6 headache specialists, 3 eye doctors, an allergist, and an endocrinologist without much relief. The diagnosis I was given was chronic migraines or potentially hemicrania continua. I recently found out that I had a small natural gas leak in my apartment (3 weeks ago). I was ecstatic because I was hoping that was the cause of my headache problems. Although the headaches have lessened, they have not disappeared completely. I am still also having the eye pain sensation. I was curious about the CSF leak because I had an epidural in my back right before my symptoms started last December, and I also had a head trauma about 2-3 years ago. I am wondering whether a leak could be contributing to my problem? Does a leak continue indefinitely or would you think it would have subsided? (I also had another epidural about two months ago.) I had a brain MRI early on and also a cat scan of my sinuses and both came back fine. Thanks!
