I tried Grape Seed Extract (gave me headaches), Inosine (didn't do anything), Topricin cream (didn't do anything). I did a big chiro package without noticing a substantial change. That being said, I have idiopathic small fiber, possibly a mild case of Fabry's disease, which docs are exploring and testing for now.

Since you have diabetes, some of the nutrition stuff may help, like vitamin D and b12 if you're low, and low carb to minimize blood sugar spikes seems to help most diabetics control symptoms. I feel worse if I eat a big meal even though I'm not diabetic. Hope you find something that works for you : )
