Had one on Wednesday but received no after care advice. I go back to hospital on Tuesday to have the stitches out but I'm struggling with how to look after the inside as it's got a scab over some stitches which keeps pulling at them every time I yawn and making them bleed. Would it be ok to use sterimar & hydrogen peroxide just to clean it out a bit and promote healing? I wouldn't poke anything in there just clean the bits I can see.
