what causes pain on left side of abdomen diarrhea
In men, a testicular infection, tumor or twisting of the left testicle commonly causes pain that radiates from the testicle into the left side of the abdomen and back. When to See Your Doctor. Call your doctor right away if you develop abdominal and back pain, especially if it doesn't go away in a few days or worsens.
Diverticulitis is a common cause of left lower abdominal and back pain, and an increasingly frequent reason for hospital stays. As you age, small pouches can develop along the walls of the colon. Most commonly, these pouches develop in the sigmoid colon, located on the left side of the abdomen.
The infection causes inflammation of the colon, resulting in pain in the left lower abdomen that might also be felt in the back. Other possible symptoms of diverticulitis include fever, constipation, nausea or diarrhea.
Pancreatic Disorders. 1  Inflamed pancreas. Acute pancreatitis is inflammation of the pancreas, mainly due to long term alcohol abuse or gallstones and may cause central or left side upper abdominal pain and nausea. 2  Pancreatic cancer may be preceded by long term chronic pancreatitis, but it may arise from the healthy pancreas.
Reproductive System Causes. Left lower abdominal and back pain in women could indicate a problem with the ovary or fallopian tube on that side. An infection, cyst or twisting of the ovary can cause severe pain that generally worsens over time.
