Low back pain is mainly caused by lumbar muscle strain, disc herniation, etc. Compared with kidney pain, the difference of symptoms lies in the range of pain, the nature of pain, and involving pain.
1. Range of pain: kidney pain generally refers to pain in the kidney area, i.e. the cross area between the 12th rib and the spine; while low back pain has a wide range, i.e. the area under the rib to the hip.
2. The nature of pain: lumbar pain is mostly manifested as local muscle tension, stiffness, mostly surface pain, and there can be obvious pressure; while renal pain is manifested as dull pain, severe pain, colic, the pain level is relatively deeper, and there can be pressure and percussion pain on examination.
3. Involving pain: low back pain can be combined with lumbosacral, hip involving pain or paralysis of the back of the thigh; kidney stones can cause pain in the groin area, and others may also lead to nausea, vomiting, hematuria and other symptoms.
In short, those who have the above symptoms should go to regular hospitals in time to get a clear diagnosis and standardized treatment under the guidance of doctors.
