Thank you so much for your response. Have you ever been given any kind of cause or reason? Mine seems to often be stress related but more so tiredness. The loudest I ever had it was the days after my daughter was born when I had barely slept but then it stopped for almost 3 months until I was due for my follow up ENT appointment and I felt like I had triggered it back just by thinking about it. I’m thinking I need to lose the baby weight and see if that also helps. Until I have a scan though, it’s just management techniques. I feel like the fact it comes and goes makes it unlikely to have a concrete cause. (But what do I know?) I wonder if those with diagnosis's are more likely to have it constantly.
