Omg im in so much pain. Not sure if this is spasm or something called fasciculations. I took some Bone meal calcium because I havent had dairy/calcium food items in years. I have bone/joint pain, cracked teeth and clear nails. I was taking Magnesium Oxide weeks prior for constipation and in turn, it caused leg cramps. I thought this signalled the need for Calcium. What I didn’t expect was Calcium to cause nerve pain. Its a painful zap that goes from back of neck to left side of head to my left ear lobe. If I scrunch up my ear, the pain still radiates. It also makes my left arm twitch. How do I undo this? I took two 200mg Magnesium Bisglycinate pills yesterday and it helped a little but by night fall the zapping was back tormenting me in my sleep. I may have actually felt more effects from past use of Mag Oxide, despite it causing loose stools. Im afraid of trying Mag Oxide and having it fail only for me to need Bisglycinate, causing me to overload on Magnesium. Unless thats a good thing for current issue. This is making me so anxious. Pain and lack of sleep. Did I do permanent damage to myself??
