Knee pain can be treated as follows: first, general symptomatic treatment, oral anti-inflammatory and pain-relieving drugs, such as meloxicam, celecoxib, loxoprofen sodium tablets, which can effectively relieve pain. Second, physical therapy, microwave physiotherapy or far-infrared physiotherapy, which can reduce the local inflammation, to relieve the symptoms of the knee fossa tendon pain. Third, the cause of the treatment, the knee fossa tendon pain can be due to bursitis or popliteal cysts and lead to tendon pain. If conservative treatment is not effective, surgery can be considered to remove the bursa. If the pain is caused by osteoarthritis involving the tendons in the popliteal fossa on the back side of the knee, you can take oral medications for osteoarthritis, such as glucosamine sulfate and glucosamine hydrochloride for nutritional cartilage; you can also take oral Chinese medications, such as tortoise and astragalus pellets to treat the pain; you can also close the painful spot, which can also have a good effect.
