Whether the knee pain after running can be cured by itself needs to be judged according to the cause of the disease, such as the usual lack of physical exercise caused by rest can be cured by itself, if it is caused by the knee joint disease, it can’t be cured by itself. There are many reasons for knee pain after running, such as lack of physical exercise, excessive exercise, inappropriate venues, improper shoes, no warm-up exercises and other reasons for knee pain, can be cured after rest. If the knee pain is caused by knee joint pathology, such as patellofemoral arthropathy, meniscus injury, osteoarthritis, etc., it can not be self-healing, and needs to be treated. If you have knee pain after running, you can take rest first, and the pain can be gradually relieved after resting, generally no special treatment is needed. If you usually have knee joint lesions, or persistent pain in the joints, you need to go to the hospital in time for further diagnosis and treatment.
