Sympathies on the CP surgery, had both of mine done. Nothing to do with diabetes. Riding motorcycles did me. Was risking gangrene in my left hand apparently.
After doctors referral due to thumb pain and pins and needles, on the nerve conductivity test I should apparently have been in agony with the amount of energy she needed to promote a reaction.
At the doctors, (3 days after the test) a different doc (community surgery) was asking me to move my hand in certain ways to see if it triggered pins and needles. "No point I always have pins and needles" says I. Within a fortnight I had the surgery on my left hand, I was stunned. 10 years on and I still only have limited sense from it, sometimes drop things. Imagine permanently wearing a glove, that's how it feels.
Right is better but also affected by impaired function.
LCHF has for me rot wise stopped the swelling I was getting on my left leg/foot, apart from some permanent discolouration it now looks almost normal. Losing 2 stone since October helps too.
LCHF is just a better diet, the wife is down by over half a stone as we eat the same (mostly) although she isn't dx and does eat more carbs than I do. She tests from time to time and is always in normal levels.
The best thing to do I think is to embrace LCHF as a life change, not a sticking plaster you can use as needed. Personally, I am almost certain if I went back to a regular high carb diet I would ultimately be another amputee. That makes it the long game for me, no option.
