My dad is suspected to have umbilical hernia. He never had any problem but we cud see a bump over his navel. I forced him to see a doc. He pressed it and now he is not able to eat well as he feels pain in navel and on eating feels like puking. In usg dr said nothing is showing. Now we are confused what is the problem exactly. For the time being its winters so can not consult for operation as he is old. Can we give him hot compress for pain relief? As dr has not given any medicine at all. Plz help urgent
