Hi Eddie
I fear what you are describing is indeed the early stages of peripheral neuropathy.
My problems started in exactly the same way, but I ignored them for about 2 years, and now have quite a lot of trouble with my feet and lower legs, although the similar problems I was having with my fingers seem to have cleared up.
I think that tight control of FBG levels - below 7.8 at all times, coupled with Alpha Lipoic acid and vitamin B12 helped me out, and others have reported the same.
There is a lot of information on a thread entitled "Help in dealing with Neuropathy", but the NHS attitude seems to be "yep, you're diabetic and you will just have to get used to it......"
I am type 2, diagnosed 2014 and on Metformin rather than insulin. My initial Hba1c was, IIRC around 114, but it came down rapidly when ignoring NHS advice and trying to stick to LCHF principles and my last one was 38.
HTH
