I had DS3 14 months ago, second c-section. Recovery was brilliant but over the last couple of months I have had an aching pain on the right side of my scar, internally. When I stand up there is a hard lump there but it disappears when I lie down. I'm wondering if it could be a hernia. I guess I need to go to the GP. Anyone experienced this? Would be good to hear. It isn't a great deal of pain.
