actually the insurance won't. we're on the military insurance (my dh is a marine) and they're...well they suck. i had to fight with them just to keep my ob. they wanted me to go to an ob that was over 3 hours away. that was completely out of the question for me.
i do have some sound sensitivity. if the tv is up too loud the pulsing sound/feeling in my head gets worse. i do have nausea. not as often but it hits me here and there and the dizziness is a big yes. i was just attributing the dizziness to my heart/blood pressure problem but now i'm not so sure. i'm going to try to call my gp today (and beg dh to get us new insurance) to see if i can set up an appointment and ask her about those meds.
Find a different doctor, especially if you can't get an appointment and you need relief. Your insurance company should cover more than one physician.
If you're not on a migraine prevention medication, and you do have migraines often, they can put you on a generic version of Neurotnin that'll help prevent them... or something like Frova (better than Imitrex, in my opinion) to stop a migraine if it's truly one. If your insurance covers it, definitely get a referral to a neurologist.
Do you have light/sound sensitivity? Nausea/vomiting? Dizziness?
