Given birth to a 3.44kg baby girl normal delivery with no pain relief only laughing gas which does not help at all as i was in labour for 2hours!!

However i have a question my tummy area especially the left side align with my belly button hurts but bearable. My postnatal massage lady told me that i should not feel any pain when she massage me. One more information my tummy looks like im 4 months preggy on the day i gave birth, i wasnt alarm as i thought it was normal after giving birth (my first) and my gynae even mentioned my womb is good. It worries my parents looking at my big tummy but after the massage it has shrink a lil only the pain is still there. My postnatal massage lady and parents told me that i should go and see my gynae to check.

Has anyone experience something similar? Any recommendations?
