Painful and uncomfortable areas of the knee can be treated with pain relieving creams, such as flurbiprofen baboo. The cause of knee pain needs to be sought in a timely manner, and the subsequent treatment may vary significantly for different causes. The more common causes are gout, meniscal damage or degenerative osteoarthritis of the knee joint. If the cause is gout, improve the uric acid examination; if the cause is meniscal damage, improve the magnetic resonance examination; if the cause is degenerative osteoarthritis, improve the x-ray examination of the knee joint, and then do the corresponding treatment according to the examination results. For gout, you can choose colchicine to reduce uric acid; for degenerative osteoarthritis, if it is not serious, you can inject sodium glutamate into the joint cavity and take oral glucosamine; for meniscal damage, if it is serious, you need to consider arthroscopy for surgery.
