There are a number of problems involved in this symptom alone. First of all, the most common clinical problem is strain of the lumbar back muscle and lumbar back fasciitis. This is usually caused by prolonged standing, walking or prolonged sitting, and cold and injury are also common causes of lumbar dorsal fasciitis. The next is lumbar spine diseases, such as lumbar disc herniation and spinal stenosis, which cause discomfort and bouts of pain in the lower back. There is also the condition of urinary stones, such as kidney stones. When there is no obstruction in the ureter of urinary tract stones, this pain will occur, instead of the severe pain of complete obstruction of the ureter. After this kind of back pain appears, we should do the corresponding examination, such as ultrasound of kidney, lumbar spine X-ray and magnetic resonance imaging of the back, which can basically find out the cause. Therefore, if the diagnosis is confirmed, symptomatic treatment can be taken.
