Hi @hollyo
from your description it does sound like it could be neuropathy -- have you got you BG's in range most of the time ?
i would ring and ask your DSN if you can get in to see your consultant as first choice -- or a visit to see GP as next best choice.
There are a couple of topics in the forum that discuss over the counter approaches that people have found that help. These include Alpha Lipoic Acid and Benfotiamine. The main proponent was @Tim55. Hopefully he'll see the tag and point you at his topic.
The only other thing, is, as himtoo says, try and keep bg levels in a relatively normal range.
