Hi there Jen and welcome to the forum

Joint pain is something that usually clears up with LCing, you may just be experiencing some of the symptoms of detox a little more severely than most. There's convincing evidence that grains are responsible for all kinds of nasty problems and their removal from a diet improves existing conditions dramatically.

Often joint pain can be caused by dehydration - and as you're losing a lot of fluids when you start a LC WOE drinking enough water daily is vital. Be sure you're getting at least 64 oz a day, minimum.

Taking supplements, as has been advised, is also a good idea. You can read here about dosage and timing of potassium, calcium and magnesium. Be very sure when you take potassium that you are well hydrated.

Hope you're feeling better soon
