A urinary tract is made up of the bladder, kidneys, ureters, and urethra. An infection in any part of this tract is known as a urinary tract infection (UTI). In most cases, the infection is caused by two types of bacteria, which are Staphylococcus saprophyticus and Escherichia coli. However, sometimes, it can also be caused by a virus or fungi.

Atopic dermatitis, or eczema, is a skin condition that results in red and itchy skin. This skin condition is common in children, but it can occur at any age. Chronic eczema can flare periodically and can be accompanied by fever and asthma. It has a wide range of symptoms including dry, red, and itchy skin; small, raised bumps that leak fluid when scratched, and thickened and cracked skin.

A hernia occurs when bulging tissues or viscera move away from their natural position and push through weak and open areas of the muscles. This results in swollen pockets and extreme pain. The condition commonly affects the abdomen but can also occur in the belly button, upper thigh, and groin regions.

Stye, also called hordeolum, is a kind of tiny red bump resembling a pimple that appears on the edge of the eyelids. It is a prevalent eye problem and more or less every human being has suffered from the condition once in his life. A stye is caused by clogging pores of the eyelids due to dust and bacterial infection.
