I've had that a long time...I think it was kidney stone related...I keep wondering if/when I'll pee blood again...
I've been having lots of headaches past few years...used to have them back in high school and then for years hardly had any...these are small sinus pressure like headaches...sometimes dehydration makes them worse...they last 1-3 days...once I get to two days it starts wearing me out...they'll come and go and then finally they are over...what is discouraging is sometimes I go through periods where I get these headaches every week...so seems like 40% of the time I have some sort of mild headache...tried everything...usually something new works the first time...and by the third time it does little or nothing...
