I am having tingling sensations in my head

Hi, I'm zo, 25 years old female. I've been having tingling sensations in my head for 6 months now. I've been to the doctor twice, all he does is give me vitamin tablets which don't work. (i'm going to the doctor again) My mother has epilepsy for 30 years now. She has the worst kind. I'm worried that this tingling sensation I have, might cause seizures in the future, btw I haven't had any seizures yet. I wouldn't be so worried if my mother didn't have epilepsy and recently my 2 year old nephew has been diagnosed with epilepsy, he has the kind my mother has. I've also had pins and needles sensation since i'm 18. Since the past month I'm feeling numbness in my hands and feet and tingling in other parts of my body too. I've had 2 blood test which were normal. Since all these symptoms can be caused by diabetes, I've had my blood sugar tested a few times and that is normal. The tingling sensation happens on the right side of my head. I don't feel different just the tingling sensation and I can do everything when it happens. It happens a few times a day, sometimes just once. I wonder if this has happened to any of you? Can anyone here tell me if this is somekind of epilepsy? Or will be in the future.. Any suggestions on what I should do besides going to the doctor again? And what I should ask my doctor during my next appointment..?
