Migraine With Aura :: Amitriptyline Side Effects?

Was diagnosed last year as having migraine with aura. started off with numbness all down my neck and left arm, confusion at times and the very odd headache. woke one morning and thought i was having a stroke... i was confused , completely numb and disoriented. went to A&E and was admitted for 5 days of tests and scans.

i had a MRI brain scan, MRI neck scan, CT brain scan, chest x rays, neck Xrays and every imaginable blood test you could imagine. all negative and clear, except for neck MRI showing a slight bulge in the c6/c7 disc but not impinging on any nerves.

so after seeing the neurologist i was sent home with the diagnosis of migraine with aura and given a 6 month prescription for amitriptyline.

after researching the amitriptyline i decided not to take it , as i didn't feel that the rare headaches i was getting were bad and as i have a young child with some medical issues i needed to be alert at night in case he needed me.

since june i was being suffering with a constant headache, on my left side, and when its bad it goes right in behind my eyes and across my forehead. it was coming and going but its been constant for the last few days and im wondering if this is really migraine.im also suffering from regular panic attack lately . does migraine last persistently for days or weeks, should the aura symptoms not disappear when there is no headache.... i am so scared that there is something else going on even though all tests were clear.... thinking of going to GP and maybe trying the amitriptyline but from researching it seems that preventative medication is hit or miss and usually comes with side effects.....
