The oral surgeon diagnosed this as glossitis [https://en.wikipedia.org/wiki/Glossitis]
I was concerned it could be BMS [https://en.wikipedia.org/wiki/Burning_mouth_syndrome], however, by definition, BMS has no signs (i.e. lesions) which I displayed at the onset. I am very health conscious, have taken a plethora of supplements for years and a few meds (blood pressure/thyroid) and never had issues, eat all organic, no processed food, & exercise regularly. I am unable to tell if any food, supplement or med causes or even worsens the soreness as it just hangs. It's not a burning or throbbing soreness, but rather just tender when touched or when I flex my tongue. There are no visible sign or redness or swelling at this point.
All input appreciated as to possible causes and treatment.
