I'm on the second week-they said I should start to see results on the third week.
PS. You need to do a lot of research what is causing you peripheral neuropathy.
Just to name a few:
-lack of B12 and folate
-diabetes
-nerves inflammation ( if yes, then what is causing that)
-pinched nerve on back vertebrae or neck
-guillen barre
-autoimune desease
-peripheral poor blood circulation
-small stroke
There's a lot of info on line.
Two neurologists done zillions of tests on me and couldn't figure out how I ended up with small fiber neuropathy.
