I was just gonna create a thread asking for this kind of advice.
I've got a ton of them, 1 set (horizontally across lower/mid back) is from a growth spurt where I grew a foot in 2 months and the 2nd set (posterior deltoids right by armpits and below lats) is from lifting. Plus a new one has just popped up on the front of my right shoulder
I don't like them but I guess it's kind of a compliment that I'm growing out of my skin
They are a huge eyesore and although I think they've stopped getting much bigger, I have a feeling they may keep going. I've been putting vitamin E lotion on them lately, that's prevention though, and I'd like to eradicate all of them
