Should i see a doctor if my blood sugar rose from 4.1 mmol/L to 5.9 mmol/L. Isnt 5.9mmol/L too much?

I use strips to measure sugar in blood, and also i have many diabetis sympotoms like wounds that dont heel, reeling sensation after meal, i have always been very hungry and thirsty, i feel like i need sugar every day, i can be without food, but i deffinitely need sodas every day to feel good.
