Hi,
Welcome to the forum and I am glad to help you out. I sincerely feel that such lower back pain should not be ignored. Thereâs a possibility of an infection in the urinary tract even if you donât have any symptoms of burning while passing urine. An ultrasound of the urinary tract should be done to rule a possibility of a stone in the kidneys.
A CT scan is a much more sensitive test to look for the cause of such a pain. An infection of the kidney (pyelonephritis) is one important thing which needs to be ruled out as if it is not aggressively treated, it can result in the permanent damage to the kidney.
Please consult a urologist for the same. I sincerely hope that helps. Take care.
