I dont wake up with headaches but throughout the day most days i develop a headache and get very tired when it comes on. are there any suggestions as to why this is happening?

Headaches during day: I suspect that you're experiencing muscle contraction tension type headaches if they are dull &,nagging in type and occur rather frequently. However it is advisable to have a medical examination to check for other causes before making that diagnosis. If your MD agrees with the diagnosis of stress and tension after your assessment, I recommend stress management therapy.
