XiYan is primarily associated with which symptoms?

XiYan, commonly known as the "Eye of the Knee," is a key acupuncture point located in the hollow beneath the patella. It is specifically associated with various knee-related conditions. This point is often used in acupuncture for addressing knee pain and weakness in the lower extremities, which can arise from a variety of causes such as injuries, arthritis, or overuse.

The connection to knee pain and weakness of the lower limbs is grounded in traditional Chinese medicine, which views this point as pivotal for promoting circulation, alleviating pain, and strengthening the functioning of related structures. An understanding of XiYan's anatomical location and its therapeutic benefits reveals its primary association with knee problems and lower extremity weakness, making it an effective choice in treatments targeting these symptoms.

In contrast, the other options refer to symptoms that are not primarily linked to the XiYan point, as they involve different anatomical areas and conditions unrelated to knee health.
