Hello, please can anyone help who has suffered similar symptoms?

Long story short, I had an initial throat infection January 2022, which I was treated for and swabs I have had done since show that it has gone so doctors are ruling that out now.  I've had the worst sore throat since this began, feeling like something prickly is constantly stuck in my throat.  My neck and underarm glands are swollen.  My neck feels really tight as though I'm being strangled and this too is constant.  Also the taste buds on the back of my tongue are considerably swollen and appear different to how they used to.  I have had throat swabs done, blood tests, and a camera up my nose to look at the back of my throat but nothing has revealed a cause.  I've had anti bionics, anti fungals, anti virals and now am taking lansoprazole although this too is making no difference at all.  I have been unable to work for 2 months due to how unwell this is making me feel and seem to be getting nowhere with my gp.  I also had a private consultation which felt like a waste of time.  Has anybody had a similar experience and what did it turn out to be?  X
