Michaela,
I suggest you try reducing the number if periods you have per year. I used to have significant menstrual migraines monthly. I discussed it with my gynecologist, he suggested Seasonale birth control pills to reduce the number of periods I have to 4 per year. In the US they say there is not a "direct" generic but there are other brands that do the same thing. A generic brand I receive is called Jolessa. Your gyn will probably know what is covered under your healthcare system. FYI, it took a few months for my body to adjust and stop having break thru bleeding, but now I don't have any symptoms of PMS monthly or bleeding like before, plus it helps to only have 4/year to deal with feeling like hell overall just because that's the hands women were dealt.
I use Imitrex injections too. The generic sumatriptan is available in the auto inject pen. I hate the pen, but I take what I can get I guess. Maybe try asking by the generic name? If your neuro doesn't give a s?&t then maybe it is time to look for another doctor. It took me more than one try to find a doctor who cares about my pain and overall well being. Of course, they will still throw drugs at you, but having someone who cares and is willing to try different things is a positive. I alternate the Imitrex Injection with a nasal spray called Migranal to avoid developing resistance like I did with maxalt and other oral medications. The migranal is a pain in the ass to administer, it takes 30 minutes to get your doses in. You spray once in each nostril and hold your head chin to chest for 15 minutes to prevent the medicine from going down your throat, which is nasty and you don't want. After 15 minutes you do a 2nd spray and chin to chest for 15 more minutes. Though it is pain it actually works well for me, I normally take it with 2 fioricet and reglan. I find the combination of meds with any triptan is more effective than the triptan alone. If you don't have a go to combination, you could discuss that with your neuro. Personally, Phenergan makes me feel awful so I don't want it in my cocktail, but I do well with Zofran and Reglan. If migranal spray isn't part your healthcare system, the generic is Dihydroergotamine (DHE) it also available in nasal spray. I also receive DHE in the ER via infusion with Reglan and Magnesium for status migraines. My neuro calls ahead to the ER and gives instructions. It helps with them treating me like a junkie, when I've never taken opiates/narcotics for my headaches.
Toradol injections used to help me greatly in combination with anti-nausea and magnesium injections. Then I developed NSAID induced colitis (not pretty) so no more Toradol. Funny thing, my pain tolerance levels are pretty messed up, ulcerative colitis is supposed to be an extremely painful condition, so they automatically prescribed me Percocet in the ER, I didn't even ask for pain medication. I never took it, and the entire time thought this pain isn't s&@t compared to my migraines. Sadly they take the colitis more seriously pain wise than migraine, if they only knew.
I hear you on feelings, if this is what life is like why bother. Chronic pain can take you there, I have asked myself the same questions. You should find another doctor, their job is to help you. If they can't help you or at least try, they are failing you. I am finally getting some treatments that are helping me, multiple series of nerve blocks with lidocaine, marcaine and decadron plus trigger point injections these are intended to allow for nerve inflammation to settle down, it seems to be helping some. Next is botox, I am hopeful acter seeing what the blocks started to do. Do I expect to be 100% pain free, no, but to lessen my pain intensity is a big deal. I was in a state of status migraine most of the time, with just a few days remission in between, and still am but the intensity is starting to lessen. There is a form of treatment that will help lessen your pain, you just haven't found it yet, don't lose hope.
