Left buttock pain can be a precursor to physiologic causes, lumbar disc herniation, pyriformis syndrome, and soft tissue infections.
1. Physiological causes: for example, sedentary or frequent running and jumping can cause pain from muscle strain.
2. Lumbar disc herniation: the nucleus pulposus compresses the nerves and can cause pain in the buttocks, and in some cases there is numbness that radiates to the lower limbs, which can be clearly diagnosed by lumbar MRI.
3. Piriformis syndrome: caused by chronic strain or trauma to the piriformis muscle, the swelling of the piriformis muscle compressing the sciatic nerve can cause pain in the left buttock, especially when doing internal retraction and internal rotation movements, the pain is aggravated.
4. Soft tissue infection: left buttock pain, localized redness and swelling, elevated dermatoglyphics, MRI can find local mixed signal changes.
Therefore, it is better to go to the hospital for examination if the left hip pain is not alleviated by resting.
