Oh Sparkle - it sounds like your daughter is now so much better informed than us when we were in our 20's. As I have said before all my problems seemed to have been hormone related and it is really only in hindsight and with education here that it all makes sense but years ago none of that counted for anything - the medical profession can be a bit useless regarding hormone problems now but even so it has come a long way considering where it started when I was a teenager.
I hope she will keep at her GP if she continues to have problems. All this sounds so familiar and I really don't want to hear or see anyone struggling for the 40 years like I did!
Donna-Paul - I had period problems, CF, postnatal depression, traumatic and early births, joint problems, aches pain, left-sided eye migraine, nausea, acid reflux, depression, anxiety - all of which were written off with "no idea why" - wait for it to go away and it never did until I got menopausal and got vaguely onto a fair regime of HRT. Most aches gone, left sided migraine well reduced, sleeping better, anxiety and panic attacks gone, nausea gone, acid reflux one, - still problems with fatigue and depression but reduced - still a bit unmanageable, but better.
You will get better overtime from the virus - don't let what you read scare you - plenty of rest as everyone says and also maybe the mindset of "not being so hard on yourself" - you are not well with a nasty virus and will take however long it takes to go away - sometimes we drive ourselves round the bend in frustration. Seems there are more "less common" if you know what I mean, viruses going about these days - well maybe you just hear about them more? - Its just difficult when you work, have a family and feel beyond rough. I really hope it passes soon.
