I have been suffering from chest and back muscle pain for 5 years. Sometimes I wake up at night with pain and have difficulty turning over. The symptoms worsen when I stay in one position for a long time, and are relieved after exercise. In order to alleviate the pain I play table tennis from time to time, but the sky is unpredictable, half a year ago when playing ball unfortunately sprained the back, and is still not sharp. A doctor diagnosed it as: myofibrositis. I went to the rheumatology department of our second hospital in Hebei province to have some related diseases examined, ruled out ankylosing spondylitis, the doctor diagnosed me as suffering from myofasciitis and prescribed blood activation. The doctor diagnosed me with myofasciitis and prescribed blood-boosting and pain-relieving drugs. Is it myofasciitis? Can I be cured? Chest and back pain is only one of the possible causes of rheumatic and immune diseases. Chest and back pain is divided into mechanical back pain, non-mechanical back pain and other causes of back pain. Mechanical back pain is the most common and generally accounts for 97% of back pain patients;, it is usually aggravated after activity and reduced after rest, which does not fit your performance and can be disregarded. Non-mechanical back pain accounts for only 1% of all back pain;, with tumors accounting for 0.7%;, your history is 5 years old and tumors are very unlikely. Infection accounts for 0.01%;, but there are usually inflammatory manifestations such as fever, which you also do not have and can be ruled out. The rest are inflammatory joint diseases, such as ankylosing spondylitis, psoriatic arthritis, Ritter syndrome, and inflammatory bowel disease. Other causes include kidney disease, aortic aneurysm, etc. Myofasciitis is usually found in the lumbar and suprailiac regions, and is rare in the thoracic back, and has a pattern of heavy in the morning, light during the day, and heavy again in the evening, and prolonged immobility or excessive activity can make the pain worse. Your description is rather simple, can you add? Some rheumatic immune diseases, such as Ritter’s syndrome, are serum immune negative, i.e. the rheumatic immune indexes are normal and there are no positive results, but they may also be rheumatic immune diseases. So you can’t simply rule out rheumatic immune diseases 100% based on the indicators are normal. It is recommended that you go to the rheumatology department of a well-known hospital for formal examination and exclusion. If you need, you can contact me by phone and I will talk more about it. I hope it will help you and wish you a speedy recovery!
