Just wondering if anyone that has idopathic snf has been diagnosed with pre-diabetes? If so have you found that the metformin helped the burning in your feet /legs? I'm on the low side of the pre and I truly think that the elevated glucose level was just enough to make my feet/legs burn. The burn is not completly gone but it is much more bareable , not near as bad at night and i can sit for longer times with out burning . I"m also taking supplements but the metformin was after I'd been on supplements which i saw an improvement but the metformin seems to really have made a huge difference .
