Caution on Calcium Suppliments... I have had a long standing problem with Osteopenia. I am sorry I can not give you more advice. I am complcated at 90 years old. I was getting the yearly infusion into my veins with flowmax?. I had a bowel obstruction in 2018. I went to the hospital and they got me unplugged.Ha Now I developed leg jerks they wrongly called "restless leg Snydrome. They kept me over into the hospital ward long enough to qualify for skilled nursing. By that time , I had developed more lower leg and shoulder weakness. After 20 days in the Taos Living Center, my Family Physician had an intern who was specializing in weakness of undetermined sources. She tested me and came up with the diagnosis os Hpercalcimia(Two much calcium was leading me down a wrong path.) I started Potassium Clo0ride ER M-20 MEG. As a retired PT, I welcomed a very strenuous program of PT and OT. I left after 100 days in a wheel chair. I have servere Lumbar problems and my L 5,S-1 sent me back for rehab. I now am in out-patient PT for a neck fusion and general conditioning. So, my osteopenia got swept into the back ground. I diagnosed myself with Myoclonic Dystonic Movement disorder and will see my neurologist next weeki. The moral of this story is, WATCH OUT FOR TOO MUCH CALCIUM SUPPLIMENT IN ANY FORM. ALSO< please check your Hyporhalumus and related effects of abnormal hand movements when you extend your arms and wrists(intention-not non intention tremor, and effects on "Restless leg sy6ndrome.(magnesium) My myoclonic jerks come any time of the day I recline and get sleepy.n they come. My increase suggest a brain tumor and that is what I am going to investigate. Any one have this? Not the medical definition but the actual 2 foot myoclonic Dystonia lighting painful jerks.
