The pancreas is transverse to the abdominal cavity, and the typical symptom of pancreatitis-induced low back pain is girdle-like pain in the lower back, i.e., low back pain in a circle around the waist. 2. The most common cause of back pain is strain on the muscles of the lower back, referred to as lumbar muscle strain.
