About the book: 2021 / Pain is a universal defense mechanism necessary for survival and one of the main ones in the body’s signaling system. Since it is extremely difficult to ignore, it quickly draws our attention to the source of anxiety and teaches us to avoid injury and danger. One way or another, everyone is familiar with pain, but what is the nature of this phenomenon? How, where and at what point does it occur in the body? What influences our perception of pain and is it always necessary to get rid of it? How did our ancestors cope with pain? The author, who has been studying the phenomenon of pain for many years, talks about all its forms: from acute to chronic, from caused by physical injuries and mental anguish to concomitant diseases. Based on research results and cases from medical practice, Dr. Lalkhen shares knowledge about how pain is formed in our brain and how other organs react to it, what conditions and circumstances intensify and alleviate pain, and most importantly, how to learn to understand pain and perceive it correctly.
