Is it lucky to have a monkey under your arm?

There is no such thing as a monkey under your arm.

The armpit is a body part, and the "long monkey" is a skin problem, which is not directly related to happiness. Rumors about "long monkeys" are called "boils" in some places and "warts" in medicine. Mainly skin color or grayish brown, the skin is convex. It usually appears on the hands and arms, and may also appear on the head, eyes, lips and feet.

The "boil" phenomenon can generally be removed by drugs, surgery, physical therapy and other methods. In addition, boils may also be caused by human papillomavirus infection, so prevention of infection is also the key.

In short, don't be too superstitious about legends, pay attention to your health and seek suitable treatment on the basis of science.
