Hi, welcome to RYL. You would be better posting this in the self harm board because this is just for technical questions really but I have alerted the mods and they will move it for you, so you hopefully get more replies.
Well done with your recovery progress. I have some small blackhead/spot type things that clear stuff can come out of but these aren't confined to my scars. Are the spots a recent thing for you? I know you said you don't talk about self harm related things openly, but would you consider speaking to your GP if you are concerned about your skin?
