Why Does Sitting on a Hard Bench Cause Pain in My Hip Bones?

The pain in your hip bone when sitting on a hard bench may be caused by the following reasons: 1. Due to excessive concentration of pressure on the hip bones, sitting on a hard bench leads to severe direct contact between the ischial tuberosities and the hard surface. This results in severe pressure on the ischial tuberosities or surrounding soft tissues, causing pain. The ischial tuberosities may also be excessively compressed, leading to inflammation and subsequent pain. This is more pronounced in individuals with thinner subcutaneous fat in the hip area. 2. It may be caused by excessive friction. When sitting on a hard bench, slight movements of the hips can cause significant friction on the compressed areas, leading to pain around the bones. 3. It may also be caused by other inflammations around the sciatic area. For example, sitting on a hard bench may induce bursitis around the ischial tuberosities, resulting in obvious pain in the surrounding area. 4. It may also be due to poor posture. When experiencing pain under the sciatic area while sitting on a hard bench, individuals often adjust their sitting posture. Avoiding sitting may lead to fatigue and damage to the joints around the pelvis, such as the posterior superior iliac spine or the sacroiliac joint, which in turn causes pain in these bones.
