Hey badger. When you mean ticking. Is it like a clock tick or your heart rate pulsating? My tinnitus is a high pitch pulsating cicada screaming.
I know this will sound nutso. But if I have my head tilt a certain way I can get that ticking, mines more like a knock but I worked it out if I open my mouth that knock knock sounds louder and comes from the left side of my neck. Not always, must be when I’ve done too much or had a long day. Like yesterday, had my last injection for the year and it was really loud. I was going to record it and ask my gp what causes it. Yes other people can hear it if my mouth is open.
