I should have said how this all started...one day about 5 years ago i was just walking down the hall at home when i got the most outrageous pain in the left side of my head...it felt like an electric shock,thats the only way i could describe it. This kept happening over about 3 days when i thought to myself oh no i bet i have a tumour or something(when you have intense head pain you always think the worst) so i went to my doctors who thought it was something else at first as i was only 33. This pain kept happening every day,goodness knows how many times a day..too many to count....anyway eventually a doctor said i think i know what it is but its unusual in someone of your age...so i was started on tegretol to start with,that worked for a few months then pains came back,changed to amitriptyline...same story,then i was given gabapentin which did work for a good while,i was taking the maximum dose a day but i began to notice my memory was going so i asked the doctor if i could get something else....so anyway i said what i am now taking...ive had 2 MRI scans which showed neuro-vascular conflict.
