Why do I get strange spasms around my temples?

I have had 2 episodes in nearly 2 weeks ,what I can only assume are spasms I do not have a headache nor do these spasms 'hurt' I feel a HUGE sense of pressure, the feeling like my head will pop its quite scary and whats worse when this happens Ive seen in a mirror that my temples actually expand (they do not pulse) so much so my partner can see a noticeable difference in shape of my head. I ve not seen a doctor, because I thought it was a freaky 5Min's but the second happened today. After these spasms Im left extremely tired in need of sleep, dizzy, blurred vision, photo-phobia to light and clumsiness

Will this pass? or is it something to go check out with doc? I am a bit nervous now.
