It has affected my walking--for my knee it is painful foot turns outward and knee is turning inward so it takes some adjusting, I have been forcing it to try to walk normally with just a limp, but then with the neuropathy the bottom of my feet are burning, sometimes hurting if I am walking too much, but that part is still manageable. Only been using the magnesium oil on the bottom of feet for about three nights now, an find it does help, the pain is not there so much and the tightness isn't as bothersome so maybe it is working, but like I said just started it three days ago.
