I'm not entirely sure why a bag popping concerns you so much if you're convinced that L Citrulline caused/started your T? You stated in a previous thread that you'd had no noise trauma and was certain about L Citrulline being the cause.
If this is the case I'd go and speak to your Dr about booking an MRI to rule some vascular issues out.
What does your tinnitus sound like?
It's not a good idea to start down the path of fearing every sound around you. Believe me, I've been there I don't wanna go back.
