I am experiencing very frequent urination today along with a really bad headache. i've gone 15 times in 4 hrs. should i be worried?

Other symptoms?: Are you also drinking more than usual? Any fevers, abdominal or back pain, burning with urinating, unintentional weight loss? The two things that come to mind are a urinary tract infection (UTI) or problems with your blood sugars. A urinalysis would be helpful in screening for both, since it could show signs of a UTI or glucose (sugar) in your urine. I would see someone now to figure this out.
