Pulsatile tinnitus: what tests/referrals should I be requesting from my GP

HI, I am a 37 year old male and I have suffered with pulsatile tinnitus since 2012. i'm looking for some guidance please on what I need to be asking for from my GP.

I feel I am not getting the correct tests/consultations as every doctor I see doesn't seem to get there is a difference between pulsatile tinnitus and tinnutus (my surgery never has the same GP so I have to restart every time I go, some even google what it is as they have not heard of it, which fills me with no confidence). My left ear is affected and recently it got unbearably loud and having difficulty locating my phone when it rings and barely hearing conversations. 

Having had some really poor experiences of ENT and Audiology, I went to see a private audiologist recently, who also worked in Audiology for 15 years. He was concerned that this was being treated as purely tinnitus and that some of the underlying causes don't seem to have been checked. When I read online ,both NHS/Australian/American medical sites, they all seem to contradict each other. I want to know what tests I should be requesting and why if anyone could please help as my GPs don't seem to get it. What has occurred so far:

1 - in 2012, after leaving the gym I noticed a heartbeat in my ear, which didn't go away. I went to my GP, who used a stethoscope and said he could hear it very loudly. This suggests, from my own research, objective pulsatile tinnitus. 

2 - referred to ENT audiologist, he didn't speak much English so via Google Translate he told me to try a saline nasal spray for a few months and perhaps a neck massage. Nasal spray did nothing, didn't get a massage. Hearing test, slight conductive hearing loss, but nothing major. I tried to point out that if the sound was played in between heartbeat noises, I can hear it, but, this wasn't listened to).

3 - In 2014 - different GP also put me on the same nasal spray and also some medication (which turned out to be for schizophrenic patients (which I definitely don't suffer with but to be fair the paperwork in the medication did say it could be used for ear issues)). She said she worked in ENT for 15 years. This did nothing, medication made me zombie like. Sent back to same ENT audiologist in point 2, who then found a bit of wax covering my ear, like a piece of dead skin, and removed. My hearing improved but tinnitus was still there. Same hearing tests conducted again, same results.

4 - Moved area, new GP in 2016. Explained I was having worsening pulsatile tinnitus, he googled it also, and then sent me to ENT. This time I had an MRI and sent for hearing test. I was told nothing was found on the MRI and same hearing results as above. They did give me a leaflet on living with tinnitus.

5 - 2018 a month ago, started getting really bad pains in muscles in left and back of my neck. I went to see a private audiologist. He said he was concerned that pulsatile tinnitus in one ear was a redflag that something might be wrong with my vascular health and the pain in my neck and that this should have been fully explored, and definitely not just be given a leaflet on tinnitus. I went back to my GP, who referred me to a tinnitus clinic at my hospital, which I go to next month, but they said they aren't specialists in pulsatile tinnitus, just tinnitus. I got to see the referral letter to which my GP put as symptoms eczema on my right hand and low self esteem.

I feel I have not been dealt with correctly, partly with me moving to a new area, partly due to miscommunication via Google translate. I am now at a point of insisting I get x,y and z tested, but, I don't fully know what x,y or z is. Does the above sound right to you guys or should I be pushing for something else? Are hearing aids available/any use? I can sleep fine, which I see on websites seems to be a difficulty for most people with PT.

Sorry for the long post...I am quite distressed by all this and when my vascular health was mentioned, I am determined to get some better answers.

Warm regards,

Jim
