I had a spinal/epidural nerve block done. I had a migrane for 10 days before the doctor would do a blood patch. I had immediate relief, but still have the same headache if I am in the sun or get hot or stressed. I start with the headache and am throwing up soon after. The shortest time it has taken is 4 hours for this headache to go away. It has been a month since my blood patch does anyone know when the headaches will stop coming?

It almost sounds like there is still a leak in there. Have you called your doctor about this? He/She may want to do another blood patch, just in case.
Why did they make you wait 10days the first time? That is rediculous. I had the same thing happen to me after a Mylo/Disco and I was back in the next day... heck, I could not handle it for another minute.
I wish you the best.
