Could midback cramps be caused by possible kidney stones. A week ago I got my long back muscles below the ribs cramped. When I tightened my abdominal muscles, I got pain in my back. The back has been weird since that.
Today in the morning I again got cramps. First slight cramping in the back, then bad cramps in my legs. When I took a warm shower, I found that the back muscles were in tight cramp. Addituonally, I had some symptom in my upper abdomen. My intestines were contracting very quikly. Some time later I got diarrhea.
My gall bladder has been taken off. Thus it is not cholelithiasis. Could this be some kind of intestinal problem? Or kidney stone? I have often hypercalcemia, and also my Na+ is sometimes above the reference. I have strong muscles but lowering of my thyroid medication has decreased my muscle tone. Sometimes my urinary bladder is weak. I have no pain in the bladder.
I am using magnesium 300-400 mg daily, and vitamin D 50 mcg. My blood magnesium has been normal. I cannot take more vitamin D, because I have hyperparatyroidism and I may get atrial fibrillation due to increasing vitamin D intake (last time at the beninning of this year, when vit D was increased to 100 mcg). During last few weeks my leg cramping has increased.
