Pain in csection scar

K • 1st baby boy December 3, 2017

It’s been 3.5 years since my csection and today my scar is hurting and then when I press on it it hurts in my stomach to my back and right side. Is this normal? Or what could it be? My obgyns nurse said it could be a pulled muscle but I don’t feel like it is since I haven’t lifted anything heavy.
