My apologies, (I must learn to double check people's gender on their profile before I make gender dependent suggestions.

I hope you get some attention from your GP soon. I'll keep my fingers crossed for you. If it is neuropathy (and I have no ideas whether it is) there are meds your GP can give you, but my honest opinion here is that your biggest issue is your out of range blood sugars and I am very sad that your GP feels unable to give you any help with this.
