Tennis elbow, also known as humeral epicondylitis, is a chronic strain inflammation of the tendon at the beginning of the local extensor muscle on the outside of the elbow joint, mainly manifested as localized local pain and discomfort. It is usually seen in tennis and badminton players, or in housewives and carpenters who use their elbows for a long time to do activities. For treatment, you can choose Yunnan Baiyao ointment to activate blood circulation and remove blood stasis. In addition to Yunnan Baiyao ointment, you can also apply localized areas of Fotarine for pain relief. In addition, it is important to take rest and avoid repeated elbow flexion. You can take oral pain medication, such as Lupin toine extended-release tablets. If these treatments do not improve significantly, local closure with lidocaine or local surgery may be indicated.
