Yes, cramp on calf and toes, as well as fingers. This happens rarely but it does happen. No idea if it has anything to do with the diabetes or not. Sometimes it happens at night. I try stretching and massaging to ease the pain.
There are a lot of different reasons for cramps, from vitamin and salts deficiencies, to drug interactions, drug side effects (statins and metformin being the most common), but those are all treatable and largely avoidable.
I don't think that Diabetes in itself causes cramps.
Personally, I eat low carb, and if I didn't supplement with magnesium and potassium and make sure I get enough salt on my food, I would get cramps regularly. But thankfully I haven't had one in ages - due to the supplements.
Leg cramps can be caused by all manner of things, including high blood sugar and neuropathy, also deficiencies in salt and magnesium.
If you take statins these can also cause cramps in some people.
I was about 20 years old and diagnosed for 2 years as type 2 and I went to see the gp as I was getting cramps in the calf's and was told it has to be with salt and since I increased my salt intake I only get them once in a blue moon but that is what it is and how to cure it just add more salt
