Conversation: The conversation between human and AI assistant.
[|Human|] I just sneezed and then had a sharp pain in my lower left abdomen. It was short-lived..like 30 seconds..but very severe. Almost felt like something ruptured. Bracing the area supportively with both hands brought a little relief. Haven t moved from the living room chair I was sitting in when it happened, but so far now the pain is completely gone. What could that have been?
[|AI|]  It could have been a spasm of the abdominal muscles because of the sudden and explosive sneezing. The sneeze reflex involves contraction of a number of different muscles and muscle groups throughout the body including abdominal muscles which contract suddenly to increase the pressure within the abdomen, which pushes the diaphragm upwards and is one of the actions performed during the sneeze. I wouldn't worry about it if the pain subsided completely within a short time. I hope I have answered your question. Please feel free to get back to me in case you have any more doubts.
