Hi everyone! I'm here with my brand new diagnosis of cluster headaches. I have been suffering for upwards of 10 years - and I'm only 24. Since the pain occurs behind my right eye, and I wear glasses, I thought it was an eye problem till this year. I went to 5 different optometrists and ophthalmologists, including a neuroopthomologist, and got several diagnoses: astigmatism, dry eyes, and computer-induced eyestrain.
But the drops and new eyeglass prescriptions and staying off the computer and switching to contact lenses, then daily contact lenses all helped minimally. Meanwhile, my eyes were basically healthy through all the dozens of tests.
Finally I started to suspect a headache of some sort. I went to a neurologist who specializes in headaches, and got the diagnosis of CH.

I am pretty confident in the diagnosis: I get severe bouts of eye pain, up to a 7 on the Kipp Scale, that can wake me up at night and are disabling. My eye feels like it is about to explode, but looks totally normal. They definitely come in clusters, with happy times in between, and only occur several times a year. The onset of the pain is severe, and disappears just as suddenly.

But I also have a mild eye pain, 1-3 on the Kipp Scale, that is much more pervasive. I feel this for weeks at a time, for a third of the days in the year. While I can function, it saps my energy. Sometimes it gets worse - to 4 or more rarely, 7 - while other times it stays at these low levels endlessly.

I'm glad to have found this site. The more I read, the more relieved I feel at finally getting the correct diagnosis.

I tried sumatriptan on my shadows and it worked. I had limited success with excedrin, probably due to the caffiene.
I live in northern NJ, and just found a company that will fill my doctor's prescription for oxygen, so I hope it works.
