Arms going numb

I'm 18 and have hypoglycemia(consistent low blood sugar). Recently my arms from elbows down are going numb ans so are my legs from the knees down. Today my ears and face are doing the same, and it feels the same way in my throat. Does anyone know if this could be related to low or high blood sugar or if it could be something else? I also have a condition that affects my joints and the way they move, so I'm worried about a pinched nerve.
