I Started Vomiting Bile And Saw The Doc On November

I started vomiting bile and saw the doc on November 25, food poisoning was considered but after 17 days of misery it was ruled out. I suffered all the symptoms except abdominal pain and chest pain. Finally after 77 days of off and on vomiting, and a loss of 35lbs was my inflamed liver and gall bladder properly diagnosed. That was on Feb 8th and the vomiting stopped that afternoon. I haven;t vomited since then and through a proper diet have regained my strength and feel great !! The ultra sound was performed on Feb 10th at Downriver Medical Associates by a Technition named Michele. She seemed very qualified and after explaining to her how long this had been going on, I asked her to tell me what she she saw on the ultra sound images...Many gall stones, of course...13 days later on the 23rd of Feb, Jesse from DMA notified me that the ultra sound images were clean, no gallstones...They explained that I probably passed them, but that doesn't explain how they disappeared from the ultra sound images...Do you have an opinion on how gall stones seen by the tech. were no longer on the images when the Doc read them ??? Curious as hell in Southgate, Michigan....Thank you...
