I have been suffering from severe headaches since last November. Painkillers don't really help, CT scan clear. Dr. prescribed 10mg amitriptyline which helped for a while. Just back from 10 days in Spain, sitting in the sun, drinking in moderation (don't touch alcohol at home as makes headaches worse) and didn't have a headache the whole time I was away. Since I've been home have had a headache every day - so fed up. Can't think what could be causing them. Please does anyone have any ideas? Nothing too stressful at home at the moment.
