12Swelling
A kidney infection would make many parts of the body swollen. This is caused by the accumulation of excess fluids when your kidneys cannot filter all of the waste and toxins in the body. You might notice this sign in some areas, such as feet, face, and hands. So, if you recently find that your shoes are quite tight, it might indicate the presence of kidney infection. Your belly might also be affected, giving it a distended and uncomfortable look. Sometimes, your jeans would shrink even a size just overnight. If left untreated, the condition would lead to some permanent changes and damages. [12]
