My blood sugar is 381 I at over 2 hours ago I feel feverish and last night my entire left leg went numb all the way to my toes I had no feeling at all then it went away. Should I go to the ER or check my sugar again?

Do you have to ask? Go to the ER now!

If you haven't, go to the ER now. It's imperative to lower that sugar as quickly as possible.
