The vague pain on both sides of the pelvis in women may be caused by the following reasons: 1. It may be caused by osteoporosis, which is common in elderly women and may cause vague bony pain around the pelvis once it develops. 2. It may be caused by relevant joint inflammation, such as ischemic necrosis of the femoral head in the patient’s bilateral hip joints or the presence of bilateral sacroiliac arthritis, which may lead to similar symptoms. 3. Some women often stand for a long time or need to do related labor, which may cause fatigue of the hip and the muscles around the pelvis, leading to the above symptoms. 4, may also be caused by long-term sitting and standing, some women need to sit and stand for a long time due to work, which may cause spasm of the muscles around the pelvis after a long time. The muscles around the pelvis may become spasmodic and lead to hidden pain.
