My left hand side of my chest has been quite itchy for the last few days, I kept checking in the mirror and couldn’t see anything. I’ve just noticed blood so have looked in the mirror and there’s a really weird mark there, plus a round lump and then a hole next to it. Does anyone know what this could be? It is below my strapping on the side of my chest. I have uploaded a photo – could you all please have a look? I thought it could be where the drains have been but it seems too low down for that and it’s not under a plaster xxxx
