The thumb is even visually different from the other fingers of the hand: it is shorter and thicker, it is detached and has two phalanges (while the remaining 4 fingers consist of three phalanges). Anatomy of the thumb is explained by its special functionality and a significant part of the physical load, which it takes over when the brush works. In this regard, a special inconvenience is experienced by a person who has a big thumb on his arm. Let's find out why the thumbs on the hands hurt.
