Jimmmy legs where are you? Need your advice. And also to anyone else that knows about this stuff. I went to a neurologist for the muscle twitching that I've had about 7 months now, along with a feeling like the muscles in my cheeks are being pulled back towards my ears, and chest pressure/feeling like I can't get enough oxygen a lot. I started taking Gaviscon a few weeks ago cause I thought maybe reflux, amazingly, it held down a lot of the twitching, and there is magnesium in gaviscon. SO i started taking 1 mag oxide once per day for about 2 weeks now and the twitching is getting less and less. Still have it, but not as bad. Also, you can't see the twitching, only I can feel it. It's in my face, thumbs, arms, hips, spine, back, knees. BUt mostly eyebrows, eyelids, around my mouth, and my thumbs and back are the hotspots. ANyways, I went to neurologist. He said i have hyperreflexia. EMG was normal. So being that my dad, my aunt, and my cousin have MS he wants MRI of brain and c spine, although he totally thinks it will be normal, and so do i. I don't even want to get it because the copay is $300 and i have a feeling it will be normal. He also ordered labs. Surprisingly, the mag range was 1.8 to 2.9 and my result was 1.9. So it's in range but low, and that's with taking the magnesium supplement, so i wonder if it was out of range low before i started taking the supplement and that;s my whole problem right there. He ordered CBC and differential, and that's normal, except again my neutrophils are low and my lymphocytes are high, and it's been like that for like 2 years now, not sure why, but i wonder if i have cyclic chronic neutropenia? My CMP... my eGFR was 57! that's low and i wonder if something is going on with my kidneys. But my BUN and Creatinine are normal. My creatinine is in range but high in range at 1.0... a few months back it was 1.1 and that was out of range. So i wonder if something is possibly going on with my kidneys, because magnesium and calcium i think are filtered through tthe tubules or something of the kidneys. Like maybe the twiching is from an acidosis? like renal tubular acidosis? I have no clue. Not all my labs are back yet. He also is checking for lymes, acetocholine stuff (myasthenia gravis). He also checked CPK and that was normal, negative Sjogrens, negative lupus, normal ANA. I think he just ordered those tests cause my sister has lupus and we have strong family hx weird autoimmune disorders in like everyone in my family. What the heck does all this mean? ALso, if something is going on with my kidneys, (which if it was, i guess it would be beginning stages cause creatinine is normal) should i stop taking the magnesium right now, cause i read don't take stuff if you have kidney disease without checking with doctor first. Also, my eGFR just 2 months ago was normal at 88, so why did it drastically drop so low in just 2 months to 57? I am 35, causasian female, fit, normal BMI, no hypertension, no diabetes, no other conditions, and my only symptom is twitching. HELP!
