I have pain in my legs, pain in my side, my eyesight is getting worse, my head is often dizzy, I have lost my appetite, I have a fever - what are these symptoms, what diseases can they cause? Asking a doctor or healer about your ailments and immediately receiving an answer about what kind of disease it is and how to treat it is the dream of many. Everyone wants to know what the symptoms indicate and how to quickly get rid of the disease. And people, unable to get an appointment with doctors, turn to the authors of books on medicine for help. For example, the famous author Alla Markova receives stacks of letters with questions every day. It is impossible to answer all questions. Therefore, she wrote a book in which she immediately answers everyone who asked her what these or those symptoms could mean. This book is not a reference book on medicine. All recommendations must be agreed with your doctor.
