I am non-epileptic with no history of it or migraines etc yet i have noticed whenever i play games on computer that involve motion or movement brings me weird sensation in frontal head to the point of nausea-like feeling. does this indicate something?

Your body is talking to you, Listen & take good notes. When does it start/stop? Where does it go? What makes it better/worse? How long does it last? Medication helps/worsens? 
If you think it is something you eat/drink/do stop it & see. If better, go back again & retest until u r convinced it is something u should stop. Then stop it. Discuss with your Drs. You all will figure it out
