Do you drink any drinks with Aspartame in ir? Like Diet Coke or in fact most other low sugar or zero cal foods or drinks? Even some medications with sweeteners have it. I ask because that stuff is really evil. After a few cans of that stuff you will if susceptible, get all sorts of stabbing and burning in your feet and even throughout your body. It takes a couple of cans to build up, but it does it EVERY time I touch it. I put it down to my Type 2 Diabetes, but when I stopped drinking the stuff, the burning and stabbing went away after a few days. Each time I get desperate for something to drink..and I go back to it, even for a short time, it comes back. You can try removing Aspartame i(f you use it), from your diet and you will definitely benefit. That sweetener is dreadful for the body, and No matter how safe they would have us believe it is, you will find many stories of people who disagree. Good luck. It costs nothing to try
