What could cause deafness in one ear? My daughter came back from vacation saying she has not been able to hear properly in one ear for the last week. She also had a toothache for most of the time away, although this went away.
I don't know if the two are connected. I'm reluctant for her to visit the doctor, or dentist for that matter, in case they prescribe drugs/antibiotics of some description.
She also went swimming and scuba diving in a swimming pool.
There are several things that come to mind. Water in the ear from the swimming/scuba diving, or possibly damage to the eardrum if she did not equalize properly when submerging.
Did she say anything about pain or feeling like fluid in the ear? Did she have any problem when scuba diving?
