Hi Everyone, In January of last year I had a terrible bout after pursuing methylation and since then I've had a variety of symptoms as seen in this thread: http://forums.phoenixrising.me/inde...g-legs-increased-heart-rate-depression.45167/ I wanted to specifically ask for everyone's advice on what other than potassium and magnesium could cause extreme muscle stiffness. Since last year I keep getting these terrible bouts of muscle stiffness in my lower back similar to flank pain, stiffness in my legs and this time around I've also gotten pretty bad shoulder pain. I sometimes get tingling legs which I believe is from my back stiffness cutting off blood flow. So far I've trialed, Potassium 500mg as NoSalt, Magnesium 200mg Citrate, 200mg Calcium, multiple times and none of them seem to have any real effect on the stiffness when I take it. I believe since my methylation attack something in my body is extremely depleted and I can't figure out what it is. I've also noticed my toenails have become much more brittle and some nails have red lines at the top which is new since last year. Any help would be vastly appreciated!!!
