However, I have all the classic indications of Horners Syndrome, with the right pupil being small, my right eyelid drooping, and no perspiration on the right side of my face. I also have a constant, severe
headache in the right side of my head, that seems to be right behind my right eye. On a scale of 1-10, that headache is an almost constant 5 or 6, and can break through to a 9 or 10. I have seen a couple of Neurologists for this, and they have not been able to do much for me.
