Can Sugar increase symptoms of neuropathy

I am 51 & was diagnosed with PN in July of last year.

I am diabetic, but my A1C has never been over 8.9 & is currently 5.4 (up from 5.0 in October.) My GP says my sugar isn’t causing neuropathy & my neurologist says it probably is.

Anyway, I take 300 mg of gabapentin, 3X a day. Until recently it was well-controlled. Last week I added magnesium glycenate to the regimen.

In December I lost my pet to old age & that broke my heart. My mother also recently had surgery & people were bringing food. So between Christmas, depression/sadness & all the extra sweets, I have had more sugar lately. I am now having the sharp pains in my feet again & really cannot stand to wear shoes/socks for long periods of time. I go back to neurologist this coming Monday.

All this to say - could the increased sugar intake over the past three months have brought on the increased pain, even if A1C is only 5.4?

Do the neuropathy socks help?

What about the creams for the feet?
