its normal I had exactly the same in my left one ,,, it felt like it was near the incision and also near the side of my boob and I also had like a bubble kind of feeling inside it when I moved my arms a certain way… honestly you will feel so many different sensations.. I even had like a grinding feeling too! they will slowly disappear and your boobs will start to feel like your own.. your own very early days so you’ve lots of strange feelings to come but don’t panic hun! and try not to over analyse them either! im 5 weeks now and I still get the odd strange feelings xxx
