Past 3 days i've been getting out of bed and having headaches. they usual return in the evening. should i be worried? not excruciating or anything.

Yes: Needs immediate attention , any one who wakes up with a headache or the headache wakes you up , pay attention to it , see you doc.

Sounds a lot : Like tension headaches. You don't describe them but usually headaches that go and come especially at the end of the day and are not excruciating are often tension . Try relaxing, maybe even yoga and see if that helps!
