Hey Jack ,
I'm on only 75mg of lyrica at night and if I miss it-i get the exact sensations you talk about!
Not that I want to promote narcotics, because they are addictive-but the fentanyl patch has reduced my severe burning by 60-100℅, depending on the day/hour/stress
I take benfotiamine and b12 for good measure-since pain relievers don't fix anything!
I'm giving self hypnosis/relaxation a shot as well.
We can't underestimate the healing power of our mind

Best,
Feather
