My DS had a lump suddenly show just under his rib cage, i took him straight to the GP who is referring us to a specialist. He believes its a diaphragmatic hernia. Most research i can find suggests he should have some sort of breathing difficulties etc but he has has no symptoms prior to this soft lump appearing at what seems like random. DS is 16 months old, active and funny little boy. The doctor was not insightful and didnt tell us anything other than he is referring us and it will end with surgery. Ive been a teary mess since then as it was such a shock, he is healthy in every other way but has had about 4 chest infections in his life which can now apparently be linked. Has anyone else experienced late diagnosis of a diaphragmatic hernia? Im extremely worried
