normal ultrasound elevated lfts

Has anyone had experience with this?  My doctor said my abdominal ultrasound was normal, but my lfts are elevated

Well it depends on how high your lfts are and how long.  Also which ones are elevated.  Do you have any other symptoms?

I am not sure how high they are, but when the doctor first saw the numbers he wasn't too  concerned he though *** may be fatty liver,  that was in December(he also checked for hepatitis,negative).  The next time was in May and he said the numbers were the same.  Now I have daily nausea, not extreme, but mild daily. Do you have liver issues?
I haven't had an alcoholic drink in eight months, but I used to be a heavy drinker. Thank you for the response
