my mother is experiencing the same situations...from the swelling to the sudden feeling of being kicked in the stomach. She ends up crying and doubled over and just ahs to wait for the pain to subside. no doctor has been able to give her a reason, and i am trying to help her figure this out. It's been happening for a few years now, shes been in the ER for it a few times, but all they do is load her up with pain meds and tell her nothing is wrong. I wish there was some sort of answers i could find online.
How old are you?
Do you think it could be heart -related pain? Difficult breathing, pain in the neck, left arm...?
