Non-stop migraines the last 2 weeks - doctors don't know what it is

[psyon]

I've had this constant migraine headache (in back of my head & neck, sometimes in temples) that started a week before last friday.  I've had 5 primary physician visits & 3 neurological doctor visits, and neither can tell me anything.  I've had MRI's run (everything was normal), there is no history of migraines in my family, my diet is actually VERY consistent and has not changed, and i don't typically get headaches or migraines.

i am not particularly stressed right now (i have a history of ulcers too, and i do not have an ulcer now), i am not depressed, am eating normally, etc....  i am a big gym-rat, so not being able to work out has really added stress because of the headache.  i have no sleeping problems.  my allergies seem to be normal & under control.  my sinuses feel fine.

symptoms: constant pain in back of head/neck.  occasionally whenever i exert force (either running, doing a push up, or anything that heightens your heart rate), i get intense throbbing in my temples & upper neck/back of head so much that it is debilitatingly painful.  My doctors put me on meds (namely painkillers), but they tried triptyphan shots (sp?) and another 3-day medication.  nothing has helped.  in fact the trypt shot actually seemed to make it worse (throbbing increased).  i've taken every type of OTC aspirin & tylenol-type drug i can think of, including the Canadian codeine 222's.  nothing.  alleve, bayer, tylenol, ibuprofen, motrin - nothing.

also normal things that i have noticed tend to help normal headaches actually make this worse.  for example, usually having caffeine seems to help me with headaches.  Now, however, any caffeine or coffee actually irritates the head and creates the throbbing sensation.  i usually enjoy traction too, pulling on the head upward from the neck, pushing front & back of head together with hands, etc.... usually pressure helps alleviate headaches for me.  in this case, it makes it worse.  Usually laying down & lying still helps my headache.  however with this one, if i stand up straight it alleviates the pain more than sitting or laying down.  It seems backward - the less blood i get to my head, the better it feels.

i guess the best analogy i can relate it to is when you scubadive and do not de-pressurize properly - i feel like the blood will go shooting out of the veins in my head.  

i am really at wits end.  as i said my doctors do not know what the issue is; i'm tired & hurting and just looking for some answers.  currently i'm on a 3-drug prescription of cyclobenzaprine (muscle relaxer), Hydrocodone (painkiller), and Ketorolac Tromethamine (i have no idea).  My only problem with this is these just help deal with the pain - they don't solve the problem.  i'm interested in solving the problem.  If anyone can be of help, i'd greatly appreciate it!

oh, other things i should add.

* i am NOT experiencing nausea
* i am NOT experiencing blurred vision
* i am NOT vomiting
* no cold sweat or chills
* no stopped-up nose or sinus congestion

so yeah, most of the migraine indicators do not align with my issues, but i assumed what i have is a migraine due to the intense pain related to and around the head.  it is like a much more painful headache, really.

i should add that i also had been given an IMITREX shot which made the symptoms worse, and most recently my neurologist prescribed AMERGE which i had taken for 3 days.  it did not make the problem worse, but it has not fixed the problem from what i can tell.

thanks in advance
