HI, thanks for using healthcare magic
It is understandable to be overwhelmed with the results and not sure which direction to go in.
stones may not cause any immediate problems , in some cases they may be discovered when doing imaging tests for other issues. You need to drink alot of water , at least 8 to 10 glasses a day, to increase the chances that they pass on their own.
(collapse of the lung) would require treatment, in some cases all that is required in physiotherapy
, you may want to visit a pulmonologist for assessment and referral first.
Your GP can do blood tests (liver function tests) to assess the function of the liver and after refer you to a gastroenterologist.
Then you can consult a general surgeon
about the umbilical hernia
unless it is associated with significant discomfort in which case you can visit one sooner.
I hope this helps
