There are many causes of knee pain, such as meniscal damage, gout, synovitis, etc. These conditions can only be determined by MRI of the knee joint, and there is no way to determine this by X-ray. You can go to the orthopedic department in time to see the doctor again, who will make a preliminary judgment with the physical examination. If you consider gout, you can have your uric acid measured. If you consider meniscal damage or synovitis, you can have your knee MRI examined promptly. If the pain is more obvious, you can use painkillers such as Lupin toine extended-release tablets. If it is gout, cooperate with colchicine to reduce uric acid. If the meniscus is damaged, arthroscopic treatment is needed for more serious cases.
