Is it migraine????????????

ello, i been having sharp pain on my left side of the head. not constantly, but coming and then going away, or just for some time, its not very painful, i dont need to take painkillers, but its so annoying, very weird pain, like sherp pain,and only one one side of my head. i heard about hte migraine, and i read that some people feel a frequent need to urinate, thats exactly how i feel! im going toilet so often, not like usual, so i was wondering if that pain and a frequent need to urinate could mean i have migraine, thanks
