Max, I'm 3 months post op for Hiatal Hernia Repair and NF. I have had the issue of burning tongue/mouth for a couple of years and had hoped and expected it to go away after surgery. I'm still having this issue. Maybe I'm still healing?? My primary care physician felt it was from the gerd but my surgeon and gastro doctor weren't convinced that it is. I know we're told it takes 6 months to a year for full recovery. Is anyone else having this issue?
