| Hi forlornjohn and Welcome to DF from a fellow Nova Scotian! (live in Fall River & work in Bedford).
Eye problems are common with diabetes but I'm not aware of one that causes a sharp pain, blurred vision and numbness.
I certainly had blurred vision due to high blood sugar when first diagnosed and it took a few weeks to come back to normal as my blood sugar stabilized
