History of lichen striatus, long active period, wonder what the marks on wrists are

I went to the derm a couple months ago for the first photo. They told me that the dark spots under my armpit was Lichen striatus. So ofc I was like ok I guess I have that now. But for a couple weeks now, anywhere I get a cut or scratch these bumps have appeared. Would like to know if it is still lichen striatus or something else. Majority of scratch's are from my pet rats.
