Occasionally had sharp lower abdominal pain fatigue few episodes of extreme bloating combined with lower back pain, recently mild headaches any ideas?

Abdominal distress: Sharp lower abdominal pains occur with irritable bowel syndrome and spasms of the intestines. They are also caused by gas entrapment especially when bloating is noted as well. Drinking hot water and applying hot water bottle helps break down the gas enabling it to be passed. Taking simethicone 1/2 hour after a meal prevents gas build up. A gastroenterologist is best to evaluate and advise you.
