I was not able to get Gralise. My neurologist said they don't prescribe it because of the cost. I was able to get tested for SCN9a and should have results in a couple months. My neurologist said he would put me on Carbamendine if the test is positive. I don't see that as making any progress though. Just a different drug with worse side effects. I also just got the shingles. I did get the vaccine in 2013 and was put on Valtrex within 3 days. This tells me my immune system is weak. Not sure which way I will turn next but will keep trying.
