You can also get a compounded prescription for a topical cream with a higher lidocaine content & other ingredients for pain. I get mine from a pain management doctor. He also prescribed compounded Ketamine troches that help a bit too. I am on 1800 mg of Gabapentin per day, as well. People tell us to exercise, but light housework & errands cause so much pain in the afternoon & night, it's not worth it. I just sold my treadmill & will try a stationary bike to strengthen my legs. My neurologist told me biking is much better than walking, as it stretches & strengthens the legs.
