Low back pain transferring to hip pain may be caused by lumbar disk herniation, lumbar dorsal myofasciitis, ankylosing spondylitis and other diseases. 1. Herniated lumbar disc: A herniated lumbar disc can compress the sciatic nerve, which may result in low back pain radiating to buttock pain. 2. Lumbar back fasciitis: Fasciitis can lead to hip pain. Fasciitis is mainly due to chronic inflammation of the fascia of the lumbar region caused by cold or exertion. This inflammation can manifest as lumbosacral pain radiating to the buttocks and accompanied by hip pain. 3. Ankylosing spondylitis: Ankylosing spondylitis is mainly caused by immune abnormality, usually tendon telangiectasia, caused by chronic low back pain, but also inflammation of the sacroiliac joints can occur leading to pain, which can cause hip pain. If the symptoms of low back pain transferring to hip pain persist without relief, timely medical treatment is needed.
