For the past 2 weeks, whenever I work out or exert myself, I get a throbbing headache in the back, right side of my head. This seems to be vascular. I'm just wondering if it's weather related. It's been colder than usual and a lot drier than usual. Does anyone else experience this with change of weather, or could it be some thing else? I don't have insurance, so I can't go to the doctor. I'm a little woried that it could be an aneurism.
