My doctors, prior to my bariatric surgery, used to put me on a lot of those meds.
Lyrica, Neurotin,
Gabapentin, Naproxone, what-not. When I was out of pain meds, I'd used to take a few more of them and they never helped. In fact, I personally think they never helped at all to control any pain. Neurotin affects nerves (I believe), so, I'd imagine if you have nerve damage, it'd help a little more. Lyrica, which is for seizures as well, has been prescribed more recently because it's the "new drug" but it doesn't have generic yet and it helped me, back in the day, maybe a littttttttle bit. I'd used to take a lot of Lyrica to help me go to sleep when the pain was really bad.
