There are three main reasons for pain on the ring jump point: First, the location of the ring jump point has more nerve and blood vessel distribution, when pressed, it is easy to produce local stimulation, so the symptoms of pain, mainly soreness and pain is relatively light, if the pain on both sides match, it is generally not due to local injury. Second, the obvious pain in the area of the ring jump point when pressed may be due to local strain, cold and strains, resulting in the formation of local accumulation of inflammatory metabolites, resulting in the formation of inflammatory edema and bruising and swelling, which can produce obvious pain when pressed. Third, because the local gluteus maximus, gluteus minimus and deep external rotators have tumors, cysts or abnormal lesions such as osteophytes and calcifications, they may stimulate the surrounding tissues and peripheral nerves when pressed, so painful symptoms may also easily appear.
