Well it really does depend on which portion of the abdomen you are referring. Left sided abdominal pain can mean many things but is usually associated with appendicitis.
You could have appendicitis, so you should go to the doctor as soon as possible to get your appendix removed. If you ignore it, you appendix could burst, making it much more complicated.
if you are a girl, it could be cramps. a little ginger ale or coke will help. if not cramps it might be a muscle strain, take it easy for a few days and if you lay on the opposite side and pain kinda moves its stool issue
Why don't you ask a real doctor, instead of random strangers on the internet who have no idea what they're talking about. Would you really have surgery on your appendix just become someone here told you to???
