Pain below the rib cage in the left back of women is generally seen in the following three conditions: the first, myofascial inflammation caused by prolonged exercise or prolonged sitting, bending, or manual labor, also known as lumbar back strain, the degree of pain in this case is relatively mild, generally dominated by soreness, occasionally stabbing pain, and light pressure pain, but there is no obvious percussion pain. Most patients will feel comfortable when tapping instead, and this condition is relatively easy to treat. The second type, intercostal neuralgia, is mainly due to pain caused by inflammation of the intercostal nerve, and is usually more often caused by viral infections, also known as herpes zoster. Thirdly, there is also a condition called renal colic, which is generally more common at night and is more unbearable when the pain strikes, and requires a hospital visit.
