i have an elevated calcium level, extremely low vitamin d level, problems with constipation, tingling numbness like a spasm in between my shoulder blades that comes all the way thru to the front of my chest, the same in my feet up to my knees when i sit for any length of time. tests showed nothing wrong with my heart, gallbladder, esophagus or stomach. also no pad or blood clots. could this be coming from some type of arthritis cutting off the circulation when i sit down for any length of time? ra runs in my family is why i am concerned.
