I also suffer from daily Headaches and Migraines. I have a Chronic Pain Syndrome similar to MS and my doctor put it down to that.
Just wondering, are you on any medications at the moment? If so, they could be causing some of your symptoms or even if you have come off them, the drug could still be in your system and making you feel like this. I know many of the pain-meds my doctor put me on had the side effect of Migraines so I decided to come off them as they weren't helping me and were causing more trouble than enough!!! I still have VERY bad headaches daily but they aren't as bad as when I was on some of the medications!!!
I agree with what the others have said - try and keep away from sunlight when you have an headache. The light makes my headaches SO much worse so I draw the curtains and stay in a dark room and it helps calm them down somewhat after a period of time. Also stress can trigger headaches and migraines so try and avoid it if at all possible (I know from experience that that is impossible though!!). I have found that when I am stressed, the headaches seem worse and the same if I am in a lot of pain.
I would definitely suggest going to see a Neurologist has they deal with Migraines and may be able to give you some advice or something to try and help you. Also, if you haven't had an MRI, I would get one just to rule out any other problems that can be easily treated.
I hope you get some answers soon and please keep us all updated. I'm here for you if you ever need someone to talk to because I DO understand!!!!
