I had never had a migraine before, but they run in my family, so I was aware of some of the symptoms. I woke up one morning with a severe headache on one side of my head, nausea, and sensitivity to light and sound, so I was pretty sure that it was a migraine. The problem was that it wouldn't go away. On the second day, I woke up and realized that I was having memory problems. I couldn't remember when my kids were supposed to be at school. By the third day, I couldn't remember how to write my name, half my face was drooping and I couldn't follow what people around me were saying.
I remember being at the hospital and having my head scanned. The next month is a blur. They tried all the migraine meds and nothing touched it. My mom stayed with us because I was totally incapacitated. I developed a myoclonic jerk in my left shoulder (my headaches are on the right) which is still with me when I'm tired.
My headache went on for months without cease. Thankfully, not with the full intensity of those first few weeks, but still with cognitive difficulty.
Eventually, it was discovered that my estrogen/Progesterone levels were off and I started taking Progesterone cream. The headache stopped immediately and hopefully I can put that chapter behind me!
