go this week so that you can at least have it on record while it's fresh - he may do some minor blood tests to see if anything is obviously amiss

have you ever been to a chiro? the way you've described the headache starting in your neck and going all the way up makes me think of the migraines i used to get - when i went to the chiro, my neck was so screwed up (from a car accident over 10 years earlier) that he was surprised i could function at all. it might be worth chiro (or osteo or similar) checking you out as well as the GP - GP's can only help with chemical migraines - many many migraines are "mechanical" and require different treatment.

hope you are feeling better soon hun - and yay to J man being there to help you out and take the pressure off today - he's right you know - REST is what you need
