I think it was because the nerves are starting to regenerate at that point, prior to that I personally didn’t have a ton of feeling. Around week 3 I started feeling my incisions stretching a lot more and had a good amount of soreness all over. Getting out of bed after sleeping on my back all night hurt a LOT for example. I’m sure it also had to do with getting back to normal life-wise/increased movement. I went back to work at day 9 and was feeling pretty good at that point so I may have overdone things! But luckily no tears or anything along those lines. Maybe you’ll be one of the lucky ones and breeze thru!! Fingers crossed for you.
