Pain in the zygomatic bone under the eyes is mainly due to two reasons: 1. The pain in this location is caused by external collision, which can lead to damage to the zygomatic bone and the surrounding muscle tissue, resulting in local bruising and swelling and inflammatory edema, which can stimulate the peripheral nerves and cause pain in this location. 2. If there is cold, it will lead to the accumulation of inflammatory metabolites that cannot be metabolized in a timely and effective manner, resulting in inflammatory edema, which will stimulate the peripheral nerves and cause pain. In addition, the cold will also cause the local muscle tissue to become more tense, resulting in more obvious pain.
