I have been having stomach problems and so far I have taken an ultra sound, ct scan and a hydroscan  all thinking this could be a gallbladder issue, but so far its not...could the problem have been the swallowing of a fish bone 4 days before the symptoms began? and would all these tests have found the bone by now, since I am just remembering about it now.
Hi, Welcome to Chat Doctor. I have read your query and understand your concern. Yes the pain could be due to the fish bone, if it has struck in the abdomen, or have caused an injury during the passage, as by now it should have got digested by the stomach enzymes. Fish bone will not be seen in these test, it will need an endoscopy. I would suggest that you take a PPI tablet like pantoprazole or omeprazole for 2-3 days, if the pain improves you need to continue it for a week or so till the injury heals. If it doesn't then go for an endoscopy.
