This phenomenon is commonly related to skin infections, such as abscesses or inflamed cysts. They form when bacteria enter beneath the skin, often through a very small wound, an ingrown hair, or blocked oil glands. The body reacts by sending immune cells to the area, which leads to swelling, redness, and pain.
In such cases, the involvement of a healthcare professional is often seen, using gloves and sterile tools. This is very important because improper handling or squeezing these formations in unclean conditions can worsen the infection or cause it to spread to other parts of the body. Hygiene and sterility are essential in these situations.
