STEP AWAY FROM THE GOOGLE BUTTON!!
Right - you do NOT have hepatitis OK!!! You say they did HIV tests when you were pregnant. SO, they will have tested for hep at the same time. They tested me for Hep despite my refusal because i have tattoos, i was a tad but relieved that i could put that particular demon to bed. Then of course i got the gall stone flare up after DD was born.
When i talk about ratios of enzymes, i don't mean in two separate tests. They usually test for two liver enzymes when they do a total profile test. It is the ratio of these to one another that can give an INDICATION, of what might be going on. They will run a test for billirubin in the blood if they do a liver function test as this gives an idication of whether or not the liver is struggling. Billirubin is what makes us go yellow in jaundice. This can happen with gallstones sometimes, it usually means, go to the doctors NOW as your bile duct is blocked. But really, don't worry about this, you would know all about it if it were i promise you.
I am very much like you, a bury my head in the sand merchant, but it is soooooo destructive, it just gets to the point where things wont go away and there is a voice in the back of my head all the time, not only is it time consuming it is soul destroying.
The problem with the internet is the horrid stuff just jumps right on out at you and its scares you shitless, you are too scared to read or believe the more logical stuff, i absolutely NEVER ever google EVER. You also have to remember that a great deal of the stuff you read on google and wikipedia is not peer reviewed, which means it could be blatant bullshit!
I think you need to go back to your doctor and have a chat with him, tell him, if he is sympathetic that you were too scared to have the retest but now you are really worried, ask for some reassurance. Tell him about the back pain. Or her!!! But while you are there, and this is really important - tell him you are struggling with anxiety generally and see about getting some medication for it. It isn't a miracle cure, but it does tame it to a managable level, most of the time (hence my thread the other day - funnily enough my lumps have gone down now i have LEFT THEM ALONE!!!).
In the nice easy logical world it would be easy to say, get your arse along and be retested but i know where you are coming from with that. It is also the not getting the results straight away.
I used to be a veterinary nurse and i have X-rayed both myself and my DP for things in the past that i just couldn't WAIT for the results for. Once because i thought i had broken my ankle (i was attacked by a dog and sprained it when i fell trying to restrain the monster animal) and once because DP had a lump which i thought was a ganglion (harmless) but he went to the doc who wouldnt tell him what she thought it was, and that he should see his own doctor ASAP - I X-rayed it and took it over to a friend of mine who is a GP to confirm it was OK. My dog died from bone cancer so i was paranoid about it I know that wasn't really the done thing to xray msyelf but there was a vet present and my GP friend had said it was OK.
