I get migraine headaches that are the result of severe muscle spasms in my neck. In total desperation one time I used my prescribed Imitrex injection and injected it directly into the muscle spasm on my neck (all other oral medications had previously made me nausious to the point of vomiting, so I knew no other oral medications would work at that point). Within 10 minutes the muscle spasm in my neck was gone completely, along with the associated excrutiating pain and the subsequent migraine headache.
I have not repeated this process since then (as I have not needed to) and I want to know if this is harmful. (I am aware that the usual injection location is on the thigh, but when I administer the injection in any other place other than directly into the muscle spasm, the medication doesn't work at all.)
With the autoinjector, the needle penetrates approximately 1/4 of an inch (5 to 6 mm). Since the injection is intended to be given subcutaneously, intramuscular or intravascular delivery should be avoided. Patients should be directed to use injection sites with an adequate skin and subcutaneous thickness to accommodate the length of the needle.
There is a risk of injecting the medicine directly into a vein which can cause vasospasm and cut off blood flow to the effected area. In the case of injecting in the neck, you could effect the carotid artery and cause blood flow to the brain to be cut off. This would be detrimental.
I would discuss this method of delivery thoroughly with the doctor before ever doing it again.

I was under the understanding that they no longer made immetrex inkections for migraine sufferers. That's great news! Using it completely got rid of my migraines. With a severe migraine you can have muscle problems in the neck area because of the pain you tend to tense up without realizing it. It is not a good idea to inject Immitrex into the neck at all. It should do the same thing to that spasm by injecting into the thigh as prescribed because once the headache is gone those muscles should relax...

The majority of my headaches start in the middle of the night. Some times I know when I'll end up with one... because I've smelled diesel or a strong perfume or candle, the weather is changing, things like that... but some of the time I think it's because I am sleeping wrong. I am OFF Zonisamide, an anti sezure medication prescribed for migraine prevention, and am on 5 mg of Flexeril every night. It's working good so far. Six migraines last month, down by half from the previous month! I do not know about doing an Imitrex injection in my neck, that sounds horrible, but I am sure it works no matter where it's used.
How often do you get your trigger point injections? I get my trigger point and nerve block injections every 4 weeks. Perhaps you should get them more often. And you should also be getting the nerve block injections at the same time.
And again, I highly recommend that you never inject it into your neck again. After having a major stroke of my carotid artery tearing apart, you would never want to have a stroke. And my stroke caused 24/7 severe migraines which are extremely hard to treat because they are from my stroke. So things could be a LOT worse for you. You lucked out this time, but next time could be a different story.
