My mom has been gone through kidney stone operation ...... she is ok up to 2 weeks and they removed the pipe after 30 days.... Then she had a pus coming from hole where the surgery has been done. Again we have consulted the doctor, they told that its an normal issue which arise in number of people and told that it gonna be wiped off after 3-4 days, But still she has a lot of pain over there , pus , and flow of fever daily and her body temperature is too high in evening times...
