I had an umbilical hernia surgery 2 weeks ago. No mesh. The lump was above my belly button, however the incision is below my belly button. When I touch above my belly button, I can still feel a lump, it is just a bit deeper down. Is this cause for concern? Was the surgery unsuccessful? I mean, the 'hernia' doesn't cause me any discomfort, granted I am basically sedentary and lift nothing >3 kg.
