Re: Major panic attack :/ always something
The metal won't cause an infection, that's due to inproper hygeine. Piercings often become infected as there are essentially wounds open to bacteria.
The high liver enzymes might symply be a reaction to having the gall bladder removed, and these levels usually return to normal within 72 hours, but can take longer (up to three months for billirubin I believe). These are usually ALT an AST. Although they raise significantly, the reason is not well understood, and it's believed to have no clinical significance. Obviously if you experience fever, jaundice, nausea/vomiting or wide-spread itching then you should seek medical advice, although it seems unlikely this will occur.
The other symptms you describe sound very much like common post-surgical issues - tissue scarring, etc. Itching is very common where surgical tape has been removed. Bruising or redness around the incision scars is normal. If it were worrying then you would have clear sign of infection.
If the pain continues regardless of position or movement, or you spot any of the symptoms mentioned above, then see your GP. In the meantime, I would certainly suggest a follow-up blood test, but urge you not to be too worried. Nothing from what you've said sounds particularly serious.
