Knee joint pain can usually be treated with ointments that reduce swelling and pain, such as diclofenac diethylamide. However, simple ointment can not cure the joint pain, so patients should go to the hospital in time to identify the cause of the disease, with other means of treatment. The usual causes of knee pain are inflammation, degeneration, overwork, and exposure to cold. Patients can use topical creams such as diclofenac sodium and indomethacin babu cream as prescribed by the doctor. These creams can relieve joint pain in the muscles and soft tissues. However, they generally do not cure knee pain. If the use of creams for knee pain is not effective, the patient should follow the doctor’s instructions for X-rays, MRIs, and blood sedimentation tests. The doctor will combine the tests to determine the cause of the knee pain. For example, rheumatoid arthritis is treated with diclofenac, ibuprofen and other non-steroidal drugs as prescribed by the doctor. In severe cases, surgery is required.
