The low back is the area between our hips and the lowermost rib cage, located on the side of the body, and pain or discomfort that occurs in this area is called low back pain. Low back pain is often triggered by muscle fatigue in the lower back, back strains or sprains, kidney, ureter, or even bladder. Other causes, such as gastrointestinal disorders, blood clots, shingles, spinal neuritis, spinal arthritis or infection, intervertebral disc problems, etc., are possible. The severity and location of low back pain is related to its underlying etiology, ranging from mild to sharp and can increase with changes in position. Some minor conditions produce less severe pain that may be exacerbated by activity. Sharp pain can be pins and needles and does not necessarily vary with position. Low back pain also often presents radiologically, reaching as far as the perineum. Treatment for low back pain depends on its cause and includes rest, physical therapy, exercise, adequate water intake, analgesics, anti-inflammatory and analgesic drugs and antibiotics, and even surgery. Right-sided low back pain Right-sided low back pain can be a result of urinary tract infections, kidney problems and gynecological lesions. Arthritis, diabetes, and low back muscle strains/sprains/spasms can all be caused by pain in their right side of the lower back or lower back. Ovarian cysts are also a common cause in women. Left-sided low back pain Left-sided pain can also originate with muscle injury and can be caused by acute pyelonephritis. Other causes include gastrointestinal disorders, kidney disease, urinary tract infections and colonic diverticulitis, and kidney stones are also common causes. Left-sided lower back pain Pain is often dull and can result from problems with internal organs or extra-abdominal structures; most are non-threatening and transient, but a few are urgent. Postprandial pain Left-sided abdominal pain often occurs immediately after a meal, stabbing or sharp enough to interfere with normal activities to the point of having to stop work and lie down. Postprandial back pain can be an organ problem, such as gallbladder, pancreas, appendix and liver. These are diagnosed mostly with the help of endoscopy, CT, ultrasound, blood and urine tests. Intermittent pain Intermittent pain is more annoying and can be intestinal irritation syndrome, medullary spongy kidney, trauma, etc. The pain can come on during the day or at night with varying degrees of severity and can interfere with sleep. Chronic pain Persistent dull pain that is not severe and is prolonged, often with persistent renal lesions such as kidney stones, kidney abscesses, kidney tumors, kidney cysts, kidney infections, and intra-glomerular nephron.
