Hello! Thank you for the query. As a reflex action, intestinal wall avoids everything what is sharp and hurt it. So usually small parts are not a danger for a digestive tract. Such parts are mixed with the stool and does not hurt an intestine. Breathing problem does not seem to be related to it either. This parts could only irritate the throat, but were not bale to get to the airwaves. So most likely your reaction is more caused by stress than by real danger. However, if you find this causes abdominal pain, lack of stool or serious breathing problem, your doctor should be visited for a checkup. Small parts should get excreted without noticing it. If you want to make sure, nothing has stuck or caused anything serious, abdominal X-ray should be done. Hope this will help. Regards.
