<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi Doctor, I am experiencing muscle cramps, weakness, tingling and numbness in my hands and feet. What could be the problem and what medication do I need?  <response>: Based on your symptoms, it seems that you might be suffering from Hypocalcemia which is low calcium in your blood. I would recommend a combination of Calcitriol, Calcium Carbonate and Glubionate Calcium to increase the calcium levels in your blood, and reduce the muscle cramps, weakness and numbness you have been experiencing.
