Md recommended i change from neurontin to lyrica (pregabalin) for peripheral neuropathy. should i expect to have decreased feelings of numbness in toes and feet?

Maybe: Both similar in their actions. Lyrica (pregabalin) newer. Both mildly effective. May or may not help the problem. Maybe some natural products such as Alpha lipoic acid may be helpful.

Different treatments: Peripheral neuropathy is when the nerves do not function as they should when the sensory nerves are affected, the sensations can range from complete lack of sensation to a "lightning bolt" pain that occurs sporadically. Both of these medications are used to treat peripheral neuropathy as well as several others. Not all medications work for everybody so use it for a while to be sure.
