Not typical migraine symptoms--need diagnosis!

Hello,

I've been getting these headaches for years now but they have recently gotten worse. I am a 24 year old female. I get pain behind my eyes (concentrated on the right side usually), a stiff painful neck and shoulders, and an overwhelming urge to sleep. I sometimes begin to yawn uncontrollably before the pain. I get no aura, and no sensitivity to light or sound, just extreme fatigue. Ibuprofen, excedrine, tylenol etc do not work. The only thing that works is a Relpax, a prescription migraine med. I get these probably an average of 10 a month. Some are worse than others but they almost always last 12 plus hours if I don't take meds. Is it migraines? My doctor told me I shouldn't need all 10 pills in a month and I find myself running out of them. Help please. Does anyone else get headaches that aren't typical migraines but only respond to prescription medication??
