Both my alt and ast levels are 80. i had an ultrsound that came back negative. what should i do now?

Recheck your LFTs: You need to get follow up liver functions(lfts) done in a couple of weeks. If the enzyme levels are declining, then you are likely to do well. If they persist to be high you may need a liver biopsy done. But this is all best handled by your doctor who should be either an internist or a liver specialist(gastroenterologist or better yet a hepatologist).
