Each of us has experienced back pain at least once in our lives. One day I was so sick that I couldn’t get up and walk to the front door. This story cost me the loss of two days' wages, plus about a hundred dollars spent on doctors and medications, and about two weeks of constant suffering. And yet my case was not one of the most severe: millions of people suffer from unbearable back pain day after day. The wide prevalence of this phenomenon, as well as the variety of causes that can cause back pain, have created a whole health trend in America. Many doctors specialize exclusively in back problems. There are special clinics for such patients. Tablets and pills, ointments and balms, sets of exercises and all kinds of devices are created to alleviate or prevent back pain. And spinal surgeries are among the most common in clinical practice. Chiropractors and massage therapists try to treat such pain. Therapists and physical therapy specialists develop various procedures and draw up instructions for patients or those susceptible to back pain. On the one hand, such great attention to this group of diseases allows us to expand our knowledge about the causes of their occurrence and fight them at a higher level.
