My neurologist told me that opiates in general do not work
for migraine
pain for many people. But, some opiates do work
for my migraine
pain. I have never been given demerol before though. Morphine, personally, makes my migraine pain worse because it aggravates all of the nausea symptoms. Morphine tends to have a very high side-effect profile in terms of stomach upset and nausea... and, when it comes to migraines... well, you know how it is.
