Should i be concerned if my fasting blood sugar is 112-117 3 days in a row?

Yes: It appears that you have an impaired fasting blood glucose test indicating that you may have pre diabetes. Please see a doctor and get HbA1C.

Borderline high: A blood test called HgbA1c would tell whether you have mild diabetes or not. Your fasting blood sugars are borderline high and nondiagnostic. Discuss this with your physician.

High sugars.: That's a bit high. You need to contact your physician for further evaluation and testing for diabetes mellitus.

Borderline diabetes: unless you checked your FSBS lessthan 2 hours after a meal. If you are concerened ie...over weight---or diabetes runs in the family---have a fasting BS run, and a hemaglobin A1C run by your doctor

See your regular MD: I'm not that worried by those numbers, but there must be some reason you are checking your sugar in the first place. Your regular physician can run some additional tests including a hemoglobin A1C and a glucose tolerance test that can give you a lot more objective information.

Fasting sugar: Yes, recommend visiting your PCP for HbA1c test.
