Which of the following points is used for pain in the ankle joints?

The point BL-60, also known as Kunlun, is commonly utilized for alleviating pain in the ankle joints. This point is located between the lateral malleolus and the Achilles tendon, making it anatomically strategic for addressing issues related to the ankle. In traditional Chinese medicine, BL-60 is not only indicated for local conditions but also serves as a powerful distal point for treating pain in the lower extremities, including both the ankle and foot.

This point has a strong influence on the bladder meridian and plays a role in relieving stagnation and promoting circulation in the affected area. Additionally, BL-60 can help in reducing inflammation and alleviating pain, which is particularly helpful in conditions like sprains, strains, or other injuries involving the ankle joint.

In comparison, the other options provided do not have the same direct association with ankle joint pain. For instance, ST-35 is related to knee issues, LI-1 is more focused on conditions involving the hand and fingers, and SP-1 is associated with spleen energy and does not specifically address ankle pain. Therefore, BL-60 is the most appropriate choice for this particular condition.
