Yes I've been misdiagnosed too. It makes it very hard to trust.
The specialist wrote to my doctors and told them what was going on with my nodes and not once did my doctor apologise for telling me I was 'imagining it'.
I'm also fairly sure that all the stuff they wrote about me being 'neurotic' and 'obsessed' was never deleted from my notes, even though I was proved correct about my lumps.
As I said, this last year has been a nightmare of GENUINE health problems made 10x harder by having to fight for referrals from doctors who didn't believe and made me question if I was going nuts. And it won't stop whilst I am still undergoing all these tests and waiting for results. My next hospital appointment is in March so I've accepted that my HA isn't going anywhere for the next 2/3 months at least. My mission is to try and stop myself going crazy until then.
Right now I still can't shake the fear that I have Lymphoma but my doctors have refused further tests in this area so that is it for now (my March hospital appointment is a follow up visit for an unrelated problem) I try to make the best of things regardless of my constant fear.
I have regular blood tests to check my white blood cell count (probably the only tests I don't have to beg my doctors for) and hope that if anything horrible is wrong with me then it will show up in my blood eventually and they might listen then!
I don't see myself as ever being 'rid' of my anxiety. I know it can be managed though because I have done so in the past so that is the best I can hope for.
I hope that you're test results are good and that you can relax a bit after that. I realise that waiting for tests and results is not easy but stopping doing everything you like between now and then will not help. I put my life on hold for months whilst I wallowed in self pity. It got me absolutely nowhere. I still had to wait just as long for my hospital appointments to come through, the doctors still thought I was nuts and I was still worried sick. Do try and find some distraction from it if possible. I was scared about telling my friends about my health anxiety but they have been great and listen to me ramble on about it all the time. They don't understand it really but some times it helps just to talk about it anyway. That's what this site is good for!
In fact I felt like much less of a freak when I found this website and read all these posts from people like me!
Good luck with everything.
