Right lower back pain can be caused by aseptic inflammation, osteoporosis, spinal disease, other diseases and other factors. 1. Aseptic inflammation: right lower back pain is mainly caused by supraspinous ligament injury and thoracic dorsal fasciitis, etc. Prolonged desk work or low back loading can lead to long time pulling of soft tissues in the lower part of the right back, triggering localized spasm, which can lead to aseptic inflammation, causing discomfort such as right lower back pain and other symptoms, which will be aggravated by overexertion and cold exposure. 2. Osteoporosis: osteoporosis often occurs in old people, which can lead to low-energy damage to the spinal vertebrae, and when the lumbar back is stressed or in light activities, it can lead to compression fracture of the spine at the back, which can cause symptoms of hidden pain in the lower right back. 3. Spinal diseases: Brucella infection, tuberculosis and tumor in the lower right back can cause pain and discomfort in the lower right back, and it is necessary to consult a doctor in time to clarify the condition for diagnosis and treatment. 4.
