I had the same experience when I was 55. I had horrible headaches and kept being told they were caused by stress, but I was under no more stress than usual and much less than other times in my life. It took a year to find the right doctor. He knew immediately what was wrong and within a month, I was back to myself. You're right; we have to fight for our own health. Too many doctors just don't care, because they are too busy.
