Riven, you need to be fit and healthy to care for your DD and family, go to the GP and demand some answers/tests. Are you eating well? Sleeping enough (as much as you can, I know)? It could just be stress, are you anaemic?
I don't mean to harp on about myself but I was suffering from a severe lack of sleep (due to dh's snoring and the baby crying next door) and I didn't realise what am impact it was having on me. Dh went away for 3 weeks and by the end of that time, my general health had improved so much, I was almost horrified by how I was feeling beforehand. I have exactly the same symptoms as you - dreadful reflux (still have that anyway), headaches, awful nausea, dizziness and sometimes vomiting.
Riven if you ever get a terrible pain under your right rib cage stretching round the back - go and demand to get tested for gall stones. Indeed, if you are as bad as you say they should have given you liver function tests already.
stemital (spelling?!) for labyrinthitis? That doesnt work for me, I have betahistine dyhodrochloride and that helps. Also if it gets really bad I end up going and they give me an injection and that helps. And sometimes bucastem for sickness.
You feel like I did last jan time - no one really knew why and I felt like a hypochondriac, a Dr suggested to me it was post viral though. It did go away luckily within time.
There's a great doctor in a super clinic in Naas in Ireland Dr Joe Fitzgibbon who specialises in chronic fatigue, and feeling tired all the time. He listens really well, and is fab according to my MIL. He has a book if a trip to Ireland is unrealistic. He's a GP also not a quack IYKWIM, so his book is very commonsensical. They'd have it in the library. HTH
you and me have quite similar health issues (didn't you also get horrid hayfever this year)?
I don't want to slag the NHS off (and I'm not going to) BUT what I have found in this country is that if you are seriously ill (like admitted to hospital), you get treated ok. If you have the symptoms you have, and you still carry on (so in your shoes, it's not like you can STOP your life and just have a rest), no-one is interested. Like you, after going back 5 times, eventually one of the doctors told me I must be a hypochondriac or depressed because if the migraine pills didn't work then it couldn't be a migraine and I must be making it up.
I can only suggest seeing another doctor or going on strike and just saying, look, sorry, I can't even get out of bed I feel so ill.
I do think stress plays a factor but what can you do?
Are you on omeprazole for the reflux? It's much better than over the counter anacids.
Sleep a huge thing but don't know how you fix that.
And have you had your eyes tested? If they haven't asked you yet, they will do and it's worth doing as poor eyesight plus tiredness can cause lots of headaches (which make the mausea worse yadda yadda).
