A colleague of mine gets them - they're quite rare apparently. He was told that painkillers don't work for these and he has triptan injections from the doctor.
I suffer cluster headaches and there is no painkiller that works. Oxygen is given in hospital and you basically have to wait for it to go. Cluster headaches cause worse pain than giving birth with no pain relief!!!
gets them every spring time and they last for 3 months. only just started seeing him too, which has made it really difficult, as he doesnt want to see me until the 3 months has passed.
