Various diseases of the abdomen can cause low back pain, but the situation isn’t very common. One clue is if pain isn’t changed by twisting or bending. When a person has back pain, we at least think if any of the following may be possible:
- Kidney Infection — rule out by Urinalysis
- Kidney Stone — rule out by symptom description [see link, see Acute Flank Pain]
- Ectopic Pregnancy — rule out by Pregnancy Test
- Ruptured Aortic Aneurysm — rule out by history, image [see link; see Abdominal Pain]
Usually it’s not hard to make these diagnoses, or rule them out, if we only think of them.
