My nerve pain has increased and I'm on the max dose of Gralise. Can switching to lyrica help, or are they too similar?

Nerve pain. Please continue to see your doctor and ask him/her about a medication change but don't make one before seeing the doc. Please also consider natural and non-invasive treatments such as biofeedback and/or clinical hypnosis ( A clinical psychologist trained in those areas can help. Peace and good health.
