To relieve pain in the left side of the abdomen, patients should drink fluids to prevent dehydration, rest to reduce pain, and eat small meals instead of large ones to help the digestive system process small amounts of food at a time, explains WebMD. It is also important to avoid foods high in fat as fatty foods may increase abdominal pain. Patients should avoid taking nonsteroidal anti-inflammatory medications and aspirin because these medications can increase pain and irritate the stomach.
Pain on the left side can often be treated with self-care at home unless patients experience nausea, vomiting or diarrhea along with pain in the left side of the abdomen in which a consultation with a medical professional is necessary, according to WebMD. Medical care is also necessary when the symptoms become more frequent or severe and if a specific area of the left side experiences increased pain.
Pain on the left side can also be treated by treating the cause of the discomfort, according to WebMD. A physician can evaluate the cause of the pain when conducting physicals, lab tests and X-rays. Muscle aches may be treated with cold or hot compresses, whereas obstructions on the left side may need to be treated with surgery.
