Suffering going into the second week now!

I have made 3 trips to the emergency room in the last week to get injections for my migraine only to get a brief bit of relief.  My medication that I take on a daily basis isn't working (duh even though the doctor thinks so).  I am sick of taking shots in my arms for relief when they only last about an hr.  I throw up, am sick to my stomache can't cope with daily life because of this and the only thing that I get is " call your family doctor to see if something else is going on".  Well I did just that.  I went to her yesterday and the only thing that she did was take blood and send me back to the hospital for an IV.  She said if I was low on fluids that this could sometimes cause migraines.  Well low and behold this did not help. Imagine that!  I can't get into see my migraine doctor ( there is at least a 3mth wait) so what am I to do in the meantime? SUFFER! Although the last trip before the IV the ER doctor did do a cat scan and it revealed nothing (they never do thank goodness) as far as a stroke, anurism(sp?) or anything of that nature.  I was given 2 shots in my rear lol of dalidud (sp?) medrol and phenergan.  These shots lasted for about 4 hrs of moderate relief but as of today I STILL have my migraine.  I am on 300 mg of topamax a day (which is the max.) .6 mg of imitrex injections take one injection then if no better in 4 hrs repeat, and axert 12.5 mg take one pill and if no relief in 4 hrs repeat.  I can't take the axert and imitrex on the same day and no more than 2 in 24 hrs.  I have tried to find a new migraine dr in my area but there aren't any that are accepting new pts. Any suggestions?????? Please help.
