Hi, im wondering if anyone else has these? I have had migraines before, and then a couple of years ago i started to have what i now think is cluster headaches, id suffer with several in a week, then went off for a couple of years, until September and again, had 3 or 4 in a week, and now again ive had 4 in 6 days. But, sometimes i get an aura, and then quickly take my ibuprofen, and i do not get a headache, it just goes. Im worried it is not a cluster headache, maybe something more serious, the Dr is phoning me on Tuesday. I looked it up and it said it is not caused by stress, but has anyone had them, and had it bought on by stress?x
