Hi. Thanks for your query. Noted the history about your daughter and understood your concerns. Noted that she had swallowed a quarter in in past and now that she is 7 and has hard stomach without any other symptoms indicate the following: It is bit difficult to palliate that a follow up X-ray is not mentioned; if done and shows that the coin is there she will need a surgery. If the coin is not present, then the obvious cause is something different. I would advise you the following in such a case: Get her to the Pediatric surgeon for clinical evaluation, examination and order the investigations as follows: X-ray of the abdomen. Tests of stool, blood and urine. Ultrasonography of the abdomen to see if there are any large intra-abdominal lymph nodes that are common at this age. Once a proper diagnosis is made it is easy for the management as per the exact cause is found.
