i had an occipital nerve block that seemed to help for about a week. after that my doctor sent me for a nerve block where they use an xray machine and inject iodine to trace the nerves and then inject steroids and lidocaine. I forget the name but this one was sucessfull for 20 days which is a miracle for me. I was told that because it was effective I am a candiate for another procedure but they do no want to continue to give me the blocs because the inject at the spine and it is too invaisive to do every 20 days. I would definatly give it a try. I pointer is to ice to injection spot as it can be painfull after it unfreezes (for both kinds). also it triggered a migraine for me each time for several days not too much worse i already have daily chronic migraine, but the benefit of the pain being lessend was worth it I live with 9/10 or 8/10 daily and i had days of 5/10 to 8/10 no 9s or 10s.

If your doctor is doing occipital nerve blocks to get rid of your migraines have you thought to ask him/her about the possibility of accipital nerve stimulators? It's a device that is implanted over the occipital nerve and essentially works as a TENS unit would provide electrical currents and stimulation to the nerve all the time.  You have the ability to control the strength and freqency of the unit.  And you and turn it on and off at will.  I had on implanted 2 years ago and it cut my migraine occurences in half. I used to have migraine pain every day at a level of 9 from 1-10 when I got then unit it was down to a 2-3.  Now I stil get common migraines and my doctor and I have those to work thru but they aren't half as bad as they used to be now that I have the ONS.  It's something to think about.  St. Jude's developed them and is continouslly doing more and more research.  I say all this because nerve blocks never worked for me they'd last for a couple weeks and then I'd have to wait 2 1/2 months for the next one.  The ONS was a godsend.
