Scar pain

I’m almost 16 post c section. I had an infection in the early days but this was treated and healed well since. I get the odd pain but nothing major. However, today I have been quite constipated and at one point strained a little harder than I normally would, ever since doing that, my scar and deeper has felt uncomfortable. It’s not enough pain that I need to take painkillers, however I’m just very aware of the area. Anyone else had this? Or is the pain just a coincidence?
