If you are experiencing discomfort in the knee joint but cannot tell what you are feeling, it is best to go to a regular hospital to have your knee examined by an arthroscopist or an orthopedic surgeon, or better yet, to have an MRI of the knee joint to determine if there are any other pathologies in the knee joint and to determine the cause of the knee discomfort before treating the symptoms. The most common cause of knee discomfort is a mild injury to the meniscus of the knee, which may be felt only after excessive movement of the joint. Patients with meniscus injuries only need to take oral horse chestnut seed extract and glucosamine sulfate, as well as other Chinese herbal medicines that have the effect of activating blood circulation and removing blood stasis, to properly relieve the discomfort.
