It is reasonable for left-sided back pain to be created by a problem with one or more extra internal organs, such as from the kidney or colon.
Lower left back pain from a kidney stone may be considered when a stone moves inside the left kidney or moves by the ureters, thin tubes connecting the kidneys to the bladder. Other symptoms add pain with urination, pain urinating despite a persistent want to do so, blood in the urine, and vomiting and/or nausea.
An infection in the left kidney can make dull or severe lower left back pain. Kidney infections normally start in the urinary field and bladder, and from there can flow to the kidneys, making local inflammation and pain in the kidney. Further symptoms may add fever, vomiting and/or nausea, and painful or stinging urination. Pain is typically felt next to the spine above the hip and typically worsens with flow or pressure.
Fibroids and endometriosis, two general conditions in women, can make lower left back pain. Pain from endometriosis is normally sporadic, sharp and stabbing, and is made by excess uterine tissue developing outside the uterus. Other symptoms may include abdominal pain, fatigue, and hard pain with menstruation. Fibroids—typically good masses growing in the uterus—can cause lower left back pain, as well as abnormal bleeding, frequent urination, and pain with the association.
An inflammatory bowel infection, ulcerative colitis is marked by determined inflammation mostly in the large intestines, also called the colon. Inflammation usually produces chronic digestive problems such as diarrhea, rectal pain, and weight loss. Abdominal cramping is a normal symptom of ulcerative colitis, making sharp back and abdominal pain on one or either side of the body.
One-sided lower back pain can happen during pregnancy as the baby grows and the mother’s body provides. Pain can differ from a dull, persistent ache to sharp, stabbing pain. Exercise, stretching, rest, and some complementary therapies can assist ease the pain.
This condition includes inflammation of the pancreas, which may cause higher abdominal pain that spreads to the lower-left quadrant of the back. Patients may explain the pain as a dull feeling that may be increased by eating, particularly foods high in fat.
A careful diagnostic method by a qualified health specialist should verify for the above, and additional, possible causes of lower back pain. Sometimes, additional testing such as x-rays, CT scans, and/or blood tests may be suggested. It is important to seek help medical care if the above conditions are assumed.
