I was having that stinging feeling on and off for a couple of days, mine did go though, think its just your skin knitting back together where the incision is. Guess if you think about how you feel off you cut your finger or knee, that stings after too whilst it’s healing, same goes for your incisions. As for the stretching pulling feeling your getting, I get that slightly too but again, I don’t think it’s anything to worry about. I’ve hardly stretched or lifted my arms that high for a week nearly now so I can’t of pulled anything I hope! Just don’t be tempted to lift to high to quickly or stretch, even if you feel ok to do so, don’t!! It’ll get better hun, I’m a week post op tomorrow and although I’m still in some pain and my muscles are MEGA stiff(I had unders) it’s slowly improving each day
