I have it for years. Well before MS. I finally got the VA to say it is military related. Go on YouTube and look up "white noise". You need a background noise to mask it. It is annoying. But a background noise helps. I've had it for 20 plus years. Constant 24/7. Does it affect your hearing? My hearing aids have a white noise program that runs along with them. Go see an audiologist. Check it out.

I have had it for over 20 years. It is MS related and no any fun. I never have a quiet moment. I go to sleep with the TV on. I went to an ear specialist, not just an ENT and there was nothing he could do. It also resulted in earring loss.

Acupuncture, or go to some one that give massages. It’s called cranial sacral massage. . warm compress

Go run the tap it is a great distraction

Just noticed it again after reading this lol
