Buzzing sound

Hello gentlemen’s,

I had a ear surgery on 8 dec 2015. Till today i am fine 25 july 2018, almost more that 2+ year. Since couple of days i got a cold and due to which i feel very loud buzzing sound, which prevent me to listen properly. I feel like i landed on the same page where i am untreated with ear. That noise is very irritating and i am not abe to focus on work.

I know after cold you don’t hear properly but this time i am feeling uncomfortable with this buzzing sound.this buzzing sound is too loud right now.

Can anyone suggest is that normal or is there any reason to worry?

Look up Tinnitis ...hopefully yrs goes away. Iv had mine 4 over 2 yrs after having a catscan an major stress...

Can we have a resurgery in same ear after 2 year.
