I was searching online to find some answers to my 'migraine' situation and I came across your post.
It seem to me I am going through the same problem as you were.
Did you ever figure out what was the cause of your severe headaches? If not how did you deal with them, manage the pain?
I have gone to my doctor several times and have only prescribed me amitriptyline and propranolol and told me to go to a massage therapist. Which so far none seemed to work. I have been fighting this battle for approx. 10 months now and don't know what else to do.
Please if you can give me any advice at all I will be at most grateful.
