Hyperacusis post ear wax syringing.

Around a year ago , had a right ear blockage . Settled on its own in 4days .Jan 2025, again the same problem cropped up . General physician prescribed wax drops , cold meds and antihistamines for 5days. In 2 days the ear popped open and was ok. 10 days back , inserted a q tip to clean ear wax , it went back to being blocked . Put the drops for 2 days , on no relief consulted with a ENT surgeon . He said ear wax obstruction and flushed it out with water via syringe . A black hard mass appeared on the tray and my voice echoed as I further spoke . 5 days of antibiotic drop was prescribed . As soon as I came home , I noticed a heightened sensitivity to sound : water falling from tap into ground , utensil sounds were more louder and sharper . Digital audio from screens felt different . I don't have tinnitus nor any hearing problem but this sensitivity to sound is really bothering me . Been a week of the procedure , how long it will take to subside on it's own or do I need to do something ?
