My sister is 30 year's old, apparently before 6 months ago, his stomach is full with acidic water. When we consult with the doctor, doctor says that she is suffered with tb and she also take 1 month medicine for the tb but when we think that she didn't get any effect through that medicine then we consult with other doctors and then he told us that your sister is suffered with the cancer. But when we consult with the aiims's doctor's and they already done approximate all the test some of the example is ugie colonoscopy usg pelvis but all the result is normal and they told us that your sister haven't suffered through cancer. But still my sister's stomach have yet the acidic water and that water is always occur within just 1 to 2 weeks. Can you please consult us what we do asap.
