The vague pain on the right side of the upper point of the pelvis may be due to lumbar muscle strain, or abnormalities such as lumbar disc bulging or protrusion, and may also be caused by ankylosing spondylitis, etc. It is recommended that a clear diagnosis be made and treatment be actively carried out through relevant examinations in a timely manner. 1. lumbar muscle strain: the right side of the upper point of the pelvis is the junction of the lumbar and sacrococcygeal regions, and muscle strain can occur due to frequent sedentary, lack of exercise, excessive stretching, etc., which may lead to aseptic inflammation of the soft tissues of the lumbar region, thus causing vague pain on the right side of the upper pelvic bone point. Patients are advised to strengthen their exercise and reinforce the muscle strength of the low back to avoid painful episodes. Under the guidance of the doctor, the small flying swallow movement can be performed, and also through hot compresses or other physical therapy to reduce the discomfort symptoms; 2, lumbar spine disease: when the patient has a bulging or herniated lumbar disc, because the bulging or herniated part will stimulate the surrounding muscles or fascia and affect the local nerves, the patient may also have lumbosacral pain, and some patients feel vague pain on the right side of the upper point of the pelvis. The lesion can be clarified by CT examination of the lumbar spine, usually pay more attention to rest, and when the pain is severe, oral non-steroidal anti-inflammatory drugs, such as etoricoxib and celecoxib, can be taken under the guidance of a doctor to inhibit local inflammatory mediators and reduce the pain symptoms of patients; 3. Immune diseases: for patients with ankylosing spondylitis, inflammatory factors cause stimulation of the nociceptive nerve, and painful symptoms can occur. When chronic inflammation appears near the lumbar spine, it can manifest as pain and soreness in the sacroiliac region, and the patient will feel a vague pain on the right side of the point above the pelvis. For early patients, nonsteroidal anti-inflammatory drugs can be administered as prescribed to inhibit inflammatory mediators. As ankylosing spondylitis may lead to changes in the spine, orthopedic spine surgery is required if necessary to relieve the patient’s discomfort; 4, neuroinflammatory diseases: patients with intercostal neuritis, when intercostal neuritis pain occurs, due to the proximity of the upper right side of the pelvis to the intercostal tissues, it may cause involvement neuralgia in this area; 5, other: vague pain on the right side of the upper point of the pelvis may also be a lesion of the right hip or pelvic bone fracture, kidney disease, gynecological disease and other causes, should promptly go to the hospital to clarify the cause and receive standardized treatment to avoid further aggravation of the condition.
