I stumbled onto this website when google brought me here to http://forums.welltrainedmind.com/topic/237047-why-would-i-get-a-headache-every-evening/ The thread is archived. So if the user @ManagerMom is around who posted Can you please come back and tell me what of 250 mg do you take everyday ? On to my question - I get headaches every evening. Google-fu shows these are tension headaches, but most days I am not even stressed! I am very well hydrated through out the day. Being a vegetarian, I have been on various vitamin supplements (including magnesium and B12) for a long time. I have inflamed turbinates for which I take a steroid nasal spray every night. I have sleep apnea but due to using a CPAP machine, the AHI every night is way less than 5 (less than 1 actually) and I have good sleep every night. My diet hasn't changed, my alcohol/nicotine/caffeine intake hasnt changed for years. I am a diabetic but my glucose is very well maintained. It started about 10 months ago it would begin with a buzzing feeling around my crown towards the end of my day at work. These days its just the temples that are 'sore' I apply some white flower oil and it seems to help. But I want to understand whats going on with me and the GPs have no answer :( I also had a sinus CT done and everythings okay in that department. Any help please :(
