Can a lot of sedation given cause tinnitus in ears the next day.

Not sure...: I'm not aware of any direct relationship between sedation and tinnitus. What kind of sedation did you have? By which route? I.V., or oral, or by inhalation? And what procedure did you undergo? Your tinnitus may be due to several things, among them the drugs you were given, any postoperative pain medicine you may be taking, or even the procedure you underwent.
