Why do i always have a bad headache? nearly every day and night

Several reasons: There are several reasons behind the occurrence of head pains ranging from genetics, muscle contractions, stress, sleep disorders, teeth grinding, trauma, and different medical illness. The exact causes of headaches aren't known. From the sounds of it, you seem to be having chronic migraines. Consult your pcp or a headache physician.

Headaches: Your headaches could be coming from tension, dehydration, lack of sleep/poor sleep, skipping meals, stress, teeth grinding, sleep apnea/snoring, or chronic sinus problems among other things. See a doctor to get checked out so you can get som ehelp for your headaches.

Chronic daily HA's: Your pattern is one that will unlikely depart on it's own, and needs meds to break up. Some pts develop this pattern secondary to consistent use of analgesics, even tylenol, (acetaminophen) but you need to pin down the underlying cause, and go from there. Many different reasons can be listed, and your doc can sort out.
