I have had daily headaches since my fall 9 months ago. I have been trying to lead a somewhat normal life. I have been adding exercise as much as 4-5 days a week. A couple of days ago I thought I would give running a try on my treadmill. I ran/walked for 30 minutes and then threw in some 15-30 second sprints. It felt great at the time, but that night I got the start of a migraine and yesterday was awful. I had to go to work and suffered the whole day. I have had migraines in the past (2-3 years ago), but nothing since then. I keep thinking that 9 months out I should be able to do the things I did before the fall.
