Have just tried Lyrica for the first time for "nerve ending" pain. I took 25 mg. It was very effective in ridding me entirely of all pain, but I also felt the drug was possibly harming me in other ways, such as sleep disturbance, confusion, mood changes, and just feeling drugged out and tired. I have previously only gotten pain relief from probiotics, which must effect the nerve pain somehow, maybe because of GABA. Can anyone recommend other things besides Lyrica, or do you think the side effects will go away eventually?
