Question
Often when I need to focus, read or listen to something while I study, the front of my head, in the middle of my forehead and sometimes the area at the back of my head seem to suffer a sort of headache. Its not a sharp or throbbing pain but rather a tingly and mind paralysing sensation. I have been getting it for years and it is bothering. I wouldn't say it was due to stress or eyesight issues (I already wear a prescription of glasses and I get it even when I'm not stressed)... what could it be?

Answer
Nahascha,

The sensations you describe follow from contractions of the muscles at the base of the head/top of the neck.

Prescription glasses are evidence of chronic eye strain, by the way, not a guarantee of its absence.  People get used to it and no longer feel or recognize it.  Remember what you felt, the first time you put on your new glasses?

To give more of an answer, I would need to know your head position during these times, and what unconscious actions and positions, and mindset, you adopt as you go about studying and/or concentrating.
