It actually covers both. My neuropathy was so bad I was beside myself without opioids, just Lyrica and Buprenorphine. I seems to be covering both legs quite well and most of my feet pain, at least about 65-70%. This difference makes me able to deal with my feet after so many years. There have been a few tough days but that seems affected by the weather or if I am overtired. It is truly life changing, I 'm walking a mile 4xwk and doing 5 mi. on a stationary bike about every other day. Since I have been now released from restrictions as of Jan 1, I can set up my pilates machine and work on strengthening my back.
