I know how you feel davey, because I'm only 29 and recently had blood tests for an enlarged liver. I'm not overweight, and I don't drink much, so I was as scared as you. I had a liver scan - which is simple and painless (the sort of ultrasound test that pregnant ladies have), and when I was put to sleep in hospital, I had a small liver biopsy taken. There are no lasting painful effects, so please try not to worry. However, just try and keep yourself fit. If you smoke and/or drink, cut right down on it now, and keep your blood pressure down. I'm sure you'll be OK, and you can come back and tell us about it. x
