This discussion originated nearly 9 years ago and was mainly about hypothyroidism (plus a bit about tingling in hands & feet, muscle cramps). It renewed a couple days ago and now mainly focuses on muscle cramps? For whatever it’s worth I have 2 granddaughters who do cross country and have gotten plagued from time to time with muscle cramps. They have found relief from making sure they warm up before running (gentle stretching etc), staying well hydrated (electrolytes?) and consuming pickles (of all things, especially pickle juice!). The first two things just seem like common sense to me, but the pickle juice was new to me! But, guess what? I tried it and it works, quickly! I keep a big jar of dill babies or petite dills in the fridge. Good thing I love pickles. I’ve found that a few swigs of the juice can even stop muscle cramps on the spot. I classify this as something that can’t hurt, might help and thought I’d pass it on.
