<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am waking up every night with severe legfoot cramps. I take vitamins, potassium, and drink plenty of water. It only started this year. I am not do any strenuous exercise. Sometimes my hands are also cramped. I am wondering what kind of doctor I need to see and what I might be suffering from.  <response>: Hello, This condition is Nocturnal Cramps for which the actual cause is still not very clear. But as my experience goes to the clinic where I practice, I have seen cases of a similar symptom present with calcium deficiency. Hence, I would suggest you get your calcium levels checked. The normal range of Blood Calcium is 8.5 to 10.2 mgdl. You can discuss the same with your physician and get it done. Along with this, I advise my patients to have a diet added with almonds, hazelnut, cashew nut, fruits like mango, Kiwi, etc. which are rich sources of vitamin E and have found to be very useful in this condition. Start the dietary changes for two months. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
