Hello,
I have had similar experiences with muscle cramps (severe and debilitating), twitching at times, spasms so bad my feet or leg or fingers will lock in a spasm, very painful. Usually, it is in my foot or leg area and wakes me up in middle of night. Worse since having long covid. My doctor told me to take Magnesium Glycinate and Magnesium Oxide. Glycinate for muscle cramps, Oxide for Constipation. Might sound weird, but the problems seem to be related. I added in LMNT electrolytes and plenty of water all day. It seems dehydration and low magnesium in my system triggers these events. When they happen in the middle done, as painful as it is to get up and walk, I go get magnesium and drink at least 16 ounces of water and put a heating pad on the area. This has been a tremendous help. Hope this helps!
