<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am 58 years old and am presently suffering from Calcium oxalate kidney stone which is in the lower ureter for which I am taking medicines, however I often suffer from severe pain in the leg which goes after I take a calcium tablet. I was taking Shelcal 500, however I understand that taking calcium tablets can increase the risk of forming more stones. Would like to know what needs to be done since I need to have calcium supplements for my leg paim as well. Please help, I live in Mumbai India, am 58 years, Female and have suffered from kidney stones calcium oxalate once in 1986 and after that now.  <response>: Hi, Thanks for writing in. I would like to tell you that in people with calcium oxalate stones, calcium restriction is NOT NECESSARY. To prevent further stones, I would recommend the following steps:a. Chat Doctor. You should be consuming at least 3-4 liters of water in a day.b. Limit the amount of protein you are consuming: You should be having a total 2 servings of milk and milk products fishpoultrymeatlegumes to 140 g per day. Approximately, 1 deck of cards 84 g c. Limit Foods High in Oxalate like nuts, soda, carrots, beets, cauliflower, carrots.d. Limit your sodium and vitamin C intake. Avoid adding salt, pickles, papas, chutneys, I do not think that the pain in your leg is related to the deficiency of calcium. It needs an independent evaluation. You can continue taking Shell 500 as a calcium supplement would be recommended in post menopausal women. Hope this helps.
