The mother was somewhat anxious, pleading as she spoke, "Doctor, you just tell us what tests need to be done and we'll do them. Please help me, my son still needs to go to school. With his condition, he's completely unable to review his lessons, and he can't sleep well either."
Tang Xi deeply understood the mother's feelings. She gently pursed her lips and said seriously, "You should visit an ENT specialist, try to get an appointment with Director Zhang, he should be available today. Tell him you suspect it might be BPPV (Benign Paroxysmal Positional Vertigo) and ask him to take a look."
The mother exclaimed in shock, "BPPV? What kind of illness is that?"
