### input:
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.

### output:

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 + fish/poultry/meat/legumes 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.
