I split open my right upper inner arm, close to my armpit. It was deep enough for the subcutaneous fat layer to hang out about 1 inch. I went to the ER and they just numbed it and stuck the fat tissue back in and put only 3 stitches. I think he should've used 4. I have a piece of hard reddish blackish dead skin that is on my left side of the stitches. Is that normal? I will send a picture if needed. Please and thank you.
