There is a large number of misdiagnosis of ankylosing crestitis both at home and abroad, which delays timely treatment, resulting in crest deformity and poor quality of life. Therefore, the following four “early” should be achieved. 1, early detection. With the accelerated pace of life, many people tend to ignore their own body subhealth conditions, even if some small problems, will not go to the hospital, but at home to eat some drugs, “to get over”. Small problems do not care, and do not take it seriously. It is only when you can’t resist and go to the hospital for a checkup that you know there is a big problem with your body. The actual fact is that you will need to pay attention to your own body in your normal life, and seek medical attention in time for any problems, so that you don’t make a big mistake because of a small illness. In particular, patients with suspected ankylosing crestitis, or friends with a family history of hereditary, once the symptoms of back pain, leg pain, sacroiliac joint pain should be promptly checked at the hospital. 2.Early diagnosis. Early diagnosis and early treatment go hand in hand. After timely detection, we should go to the hospital for diagnosis, film examination and laboratory tests. Many patients are afraid of spending money, more than not to carry out systematic examination, which can easily lead to misdiagnosis or because the consultation items are not enough to confirm the diagnosis; and because the early symptoms of ankylosing crestitis and some chronic diseases such as rheumatoid diseases are very similar, inexperienced doctors are prone to cause misdiagnosis of the phenomenon, delaying treatment time. 3, early treatment. Once the diagnosis is confirmed, it is important to treat it in a timely manner and not to give up on yourself and not to treat it. This is very detrimental to the control of the disease, not only delayed the best time for the patient’s treatment, but also for the patient’s future life overshadowed. 4, early adherence to treatment. Many patients with ankylosing crestitis believe that early disease, as long as it is controlled by treatment, no pain can stop treatment, such a view is wrong. The actual fact is that you will be able to get a lot more than just a few of the most popular and most popular items. Only then can you effectively control the development of ankylosing crestitis and resume a normal life.
