Wow, you have a lot going on. I wonder if the sound in your neck is Tinnitus. Are you sure the sound is coming from your neck? I have Tinnitus that came on with my heart issues. Sometimes it sounds like its in my ears other times in the back of my head. When Im feeling bad its a loud wooshing sound and on a good day it sounds like a high pitched hissing.
I had vibrations in my lower torso from my waist down. That was because of nerve damage so maybe you could recall if you were exercise or doing something strenous to maybe damage a nerve. It took 3 months of Acupuncture to get rid of this.
Before being put on my heart med Propranolol, for years I would get this cold chill like symptom that would make a circle around my upper torso. Where my bra would be. It would happen at random times but was very annoying and would make me worry. Since Ive been on the Propranolol it went away.
I get tachycardia starting 10 days before my period every month. It get the worst 4 hours before my period starts spiking from the 70's to 120 or more laying in bed. We have figured out that a lot of my heart issues are running with my ovulation week and the week of my period so this has been helpful in mental prep and anxiety.
Use the tracker on this site for a few months. Document everything that happens to you every single day. After 4 months you will see a pattern in your body and its pretty amazing. I write everything down for a week and then log it in on the weekend.
Hope this helps,
Lucy
The only thing I can help with is the spelling for the procedure recommended, it is spelled :ablation. Hope I got it right, I make the strangest typos.
The main arteries in the neck are called: carotioid arteries and they are the major arteries that travel up the neck and into the head and brain. They can develop constrictions on flow and blockage (very bad) and that, I believe can be heard. I don't know if that can happen on both sides, but I'd guess it happens on one side at at time even if it can happen on both sides. I'm not stating that is what you hear in your neck, and it reads like you are getting expert medical attention, so there's little most of us on the community can add.
