I get lots of headaches and I believe theyre brought on by anxiety/stress. Its like a tight band round my head and it feels like someone is tightening the band. I take painkillers and usually the headache goes but I have had a couple recently that Ive had a problem shifting.
I dont have a dx of bipolar so cant comment on the link between that and headaches. I hope that the one youre suffering with at the moment soon goes.
