I did take it all and it didn't help and was awful.
I also posted here for help and was met resoundingly with "if your GP thinks you're a mentally unstable hypochondriac then why aren't you just accepting their professional opinion? Clearly you're mentally unwell and need drugging into a stupor". I remember one GP asking what I do for work, I told them and they said "oh, that sounds really stressful, I think it's anxiety related" so, I made a note the next time to say I don't work. When I said that I got "ah, not working must be very stressful - I think it's all anxiety related". I don't think there's an answer that can be given to that question that wouldn't elicit the same reponse.
It all started very suddenly back in 2021 (also after having Covid). I was taken to hospital by ambulance and, when I was admitted, the doctor on the ward assaulted me and lied about some things. He was the one who decided I needed mental health support (I think so that, if I reported him, I wouldn't be believed) and from that point, I couldn't get anyone to believe anything other than that I was having a breakdown. I have proof of the assault and still consider reporting him but I don't even know his name. But, even saying that you're assaulted by a doctor in a hospital makes people think you're a nutter. I've not told anyone except DH about it in real life. He's the doctor who discharged me with gabapentin, acetazolamide, pregabalin, propranolol, tramadol and amytriptaline (all to take at the same time).
When it came on again recently, I was so scared - but my GPs now are so good. I've seen two at my surgery. The first suggested cluster headaches, said to go away and research/discuss and see if that lined up with my symptoms, etc. He ordered tests anyway - which found the mild anaemia but not much else. I went away and some things lined up but others didn't. I went back and saw a different GP (because the first one is away and they wanted to see me quicker). He checked my ears and could see the fluid, reviewed my blood tests, etc. The things he recommended have changed everything in just a few days.
My chest pain has gone now, I can still feel it in my back and neck a bit. I had tingling and pain on the tips of my fingers too that would hurt when typing. The whooshing/pulsing/thumping in your ears is typical for ETD.
