Hi, thank you for posting your query on health care magic.
I can understand your concern.
You inhaled a piece of bathroom tissue accidentally.If it is in your trachea,then you might suffer from symptoms like difficulty in breathing,Noisy breathing,
Cough,etc
You feel that foreign body is just a little lower than your
uvula.There is a possibility that foreign body might have stuck in your pharynx.
I would not advise you to do anything to get it removed .And it may or may not degrade.If it gets lodged for a longer time,then there are chances of infection and it may go lower down from your trachea into lungs.
I would advise you to have a Chest and Lateral view of neck X-ray
Also advise you to consult an Otolaryngologist doctor for throat examination to look for any foreign body.
If the foreign body has reached airway,then you will need to
consult a pulmonologist ,who can remove the foreign body from your airway by
Endoscopy.
Hope this answers your question.Take care.
