Confused by ultrasound results

I have had high liver enzymes ALP and GGT for a while looks they directly point to an issue in gallbladder or bile ducts which made GP to finally request an ultrasound, I did not see the results myself but my doctor said ultrasound results for liver problems was negative and liver appears normal, that is all I got, but problem is I have started to have URQ pain since couple of days and it’s slowly increasing in intensity, could it be that ultrasound missed something? Because of ultrasound results my further care is going very slowly actually and gets me worried
