I can sympathize with you. I suffer from chronic migraines and add that on top pf everything else, Yikes. If you are like me and a big caffeine drinker, you may have lower levels than you are used to. Try hot tea. Tea has more caffeine than coffee. A cold compress to the forehead may help, also meditation. I take injections of Imutrex when my attacks occur and it makes me throw up. No more headache but then who could tell with the doubling of the abdominal pain. Keep a log if you can and find out what you did that day before, what you ate, where you were (sporting event, movie, sitting in front of a computer) and so on. Then if the problem continues, talk to your doctor or get a referral to a Neurologist. Best of luck and hope this is a temporary thing.
