Honestly, it depends on the doctor. My original doctor had been doing trans healthcare for decades, and she had it down to an art. She'd put them implant in my abdomen, I'd get a single stitch, and had to avoid strenuous activity for a couple of days, but it was otherwise it was minimal impact.
I asked her to put one in my butt cheek once. She'd never done that before, and it showed. It was a more troubled implant, and took me longer to recover from, and made sitting uncomfortable for a few days.
And my current GP who doesn't have quite the same experience as the first, tends to leave a bruise when he does the implant, but it otherwise heals the same as always. A single stitch, and a couple of days without strenuous activity.
Good to see!
