Welcome to the club. I have just same kind of headache as you have. All the meds that you mentioned have been through my system with a BIG zero effect, just my wallet weighs a little less now..
You know your triggers, what are they? whatever you mentioned thereafter in that sentence, all are symptoms of aura, just an indication that migraine band is right next corner, get ready to face the music.
What kind of chronic pain do you have? Why it's there to begin with? Do you have any other health problem, if so, what is it? You admit of sedentary lifestyle. Have you had a word with physical therapist that can suggest you exercise and/or also help you with your pain? May be you should see a pain management specialist. DW is a physical therapist and she works with a pain management doc. If these pains are not taken care of as early as possible, the brain usually tries to avoid the signals, because the overfiring of the nerves is also taxing on brain. That leads to new neural connections, ending up with pain all over. She can not help everyone but sometimes it helps to get life going.
Every neurologist is NOT a headache specialist. They know general arena but that does not mean they are experts in headache. Check out local headache centers in your neighborhood and schedule a visit ASAP. 2 days ago, my big city headache center gave me an appointment in March 2013, so you can imagine the load on these centers.
I started Mg (citrate form, vitaminshoppe brand, if you are using Magnesium oxide, throw the bottle away, read the label) about a month ago, 200mg morning and evening with riboflavin 200mg morning and evening and 400mg of CoQ10 once a day. I also haven't seen any effect as on yet but I read that it takes about 3 months to see effect. If I don't see any effect in 3 months, I plan to add 200mg of Mg-citrate in the afternoon as well for another 3 months. And then, depending on results, I continue or discontinue. Talk to your doc about it because if you have other health issue, you don't want to complicate it.
Have you figured out why do you have sinusitis? Are you allergic to something? Do you have mold in your house? Do you have deviated septum in your nose? Have you tried Indian procedure called as neti? Have someone with you if you try Neti. The first time you give a try, you will get an extremely bad/weird/unconfortable feeling all around your sinuses. Learn it well before you give a try.
What your food is like? Do you eat red meat, processed food i.e. standard american diet, all the time? May be you would like to go more veggie way. Take a look at http://www.fatsickandnearlydead.com/ movie. The guy does extreme but as long as you eat loads of veggies, you are good. I am a vegetarian for last 6 years as a result of my health issues. I don't even eat Soy (and if you are a woman, you should not either).
There is tons of hope when it comes to your migraine. Maintain a diary, you will need it when you go the specialist. If you use smartphone, take a look at migraine notebook.
