Hello, I Had C Section 4 Weeks Ago. After 2

Hello,
I had c section 4 weeks ago. After 2 weeks pp by toddler kicked my belly real hard and I feel numbness around my scar since then. I also started getting massages on my belly since few days. Is it a bad idea? How can I tell if I'm healing well on the inside?i ve been feeling just fine after 2 weeks pp. also I'm 27 yrs and slightly obese . Does age and size has anything to do with healing?

Thank you .
JJ
