Weird C Section pain

Okay so this may sound a little weird, I’m 34 and my youngest will be 12 in November, eldest 14 December, both kids born via emergency c section. The last few weeks I have been experiencing pain across my scar similar to what I felt as I was healing, I’ve had a cough for a few weeks and when I cough it feels like something in my scar is tearing or as if stiches are about to pop. My scar has always been sensitive to touch and I can’t touch it due to not liking the sensation but the last couple of weeks it’s painful to touch. When I touch it it feels bruised. Surely after so long I shouldn’t be having this type of pain? I feel a bit embarrassed to go to the Doctor.
