I feel like lobster shell has potassium so lobster bisque would fix this. However, sounds like you're on a specific diet, so probably not lobster bisque 🤔 maybe something with some sort of seafood stock like lobster shell tea but you make soup out of it 🤷🏻‍♂️

Oddly enough, I get that every once in awhile on the left side of my jaw. Also it is very unpleasurable cramp and idk why I get no other cramps anywhere else. Good luck
