Since one week, back and neck pains are 3/4 lower than previous week, I should feel great but now I have electric shocks in my head, like brain zaps. It could be described as a trigeminal pain but it is in the top left side of my skull when I move my head, eat and sometimes without doing something. The pain occurs 1 second but is very strong, a big electric "blackout". I have had such kind of problem during several weeks 3 months ago and it seems to appear and disappear without any explanation. I have seen on sprycel notice and it is written "peripherical neuropaty", could it be the case. I have taken different medication such as neurontin, pain killers....but there is no progress. Thanks in advance for your answers.
