I have been at my wit's end to figure out what's causing my severe muscle tension / cramping in the whole body including the pelvic region, face, eyes. I also sometimes get what feels like the MS "Hug" in my abdomen. It feels like, for lack of a better word, "a sustained muscle spasm". But MRI's & the EMG/NCV etc. came out normal & MS/other neurological disorders were ruled out. I am taking plenty of electrolytes incl. magnesium/potassium. I am unable to tolerate more than 400mg Magnesium in the day even though i have tried several different forms. Any more makes me too fatigued & spaced out to function. I also do epsom salt baths. What else can I do or what possibly might be causing it? I don't have any diagnosis yet though i do have low blood sugar.
