Hi AM64 / kooky,
I have sensitive feet also, with the odd shooting pain. The diabetes nurse said it was down to me rapidly getting my bs levels dropping so quickly, and should go away in time.
It's the sensitive feet which are the issue, I can actually feel every tuft in the carpet and even feel my socks. Not painful just weird.
I was offered two options to try and get rid of it quickly.
First option was cardanum oil/lotion (forgive spelling, auto correct wanted car donut

). This burns your feet and desensitises the nerve endings. You have to apply with gloves to protect your hands.
Second option was antidepressant drugs, they numb the sensitivity some how. I thought I'd try these. Had the first tablet last night and not slept, and feeling a bit quesey. We'll see him these go.
