Doctor has me testing glucose due to feeling hypoglycemic at times. when i test on right index, it's high, but when i test from the left, it's low.

Glucose testing: You don't say what "high" and "low" is. The glucometer is only accurate to +- 20%. So a value of 80 could be 96 or it could be 64. Most people will not feel symptoms of hypoglycemia unless the glu is less than 50, or even lower. Also, the symptoms of hypoglycemia are common to many other things. The L and R should be the same.
