Hello and welcome to HCM,
The character and site for headache that you have described does not seem to be due to migraine
Migraine attacks and usually associated with nausea
and an aura.
Moreover, migraine headaches
are more generalized.
Pressure in the front part of the head and behind eyes especially on doing school work may be due to a refraction
When there is change in refractive power of the eye (low vision
in common language), the muscles of the eye try to accommodate and thus cause dull pain.
So, visit an ophthalmologist for a refraction test.
I hope my answer is of help to you.
Kindly, post your feed back before closing the query on HCM.
Thanks and take care.
Dr Shailja P Wahal
