Welcome to HCM
There is nothing to be alarmed by tingling sensation
there are many causes for tingling sensation.
It is good that you are aware of diabetes
but just check your FBS and PPBS.
If they are normal you can recheck once a year .
As your father is diabetic you should take care of healthy life style like normal healthy weight,No smoking
and alcohol, Regular exercise and taking care of diet.
If it it persistant and recures then check with local doctor to see if there is any cause for it.
Goo d luck.
