Hi i have had stomach cramps for the last two days its at its worst when getting up out of a chair the pain is in my lower left hand side

Pain: Pain in the left lower abdomen always raises the possibility of a condition called diverticulitis. This would be more likely if you had pain with eating and fever. The fact that it hurts when getting up from a chair suggests that it may be muscular in nature. Any change in your bowel movements? See your doctor if the pain gets worse or changes and fever develops.
