I had to try Gabapentin and Amitriptyline (both of which I could not tolerate ) before I could be prescribed with Lyrica.
I have had no side effects from Lyrica ( it has a different delivery system from the other two.)
Lyrica has certainly helped my chronic trigeminal neuralgia.
Nerve pain is different, depending on the cause, but if your doctor has prescribed Lyrica for your pain, I would not worry about taking it.
