Thanks for posting your query here,
You have episodic chronic headache which according to your description seems like episodic tension type headache.
I would like to know following:
1) Do you have refractive error
for which you use glasses?
2) Do you take analgesic
3) Do you have too much stress?
Usually such headaches
are not serious; but if anything serious is suspected, a CT scan
of Head may need to be done.
Otherwise you seem to have healthy lifestyle.
Once I get your reply to above questions, I can answer in detail.
