Actually I want to know that, My mother has done open heart surgery before 10 years ago from cmc vellore due to some problem regarding valve. Now she is 54 years old and suffering with several problem like- chest pain, joint pain, blood clot, liver expansion time by time. Wherever I go they told Me to go CMC vellore again for consultation. But the operation relate docs are no longer exist as well doctors are also changed. So I need a suggestion. Please Help.
