Post scabies nodes

Has anyone here experienced scabies nodes on their penis? Specifically the tip… I saw my derm and she said all the bugs were gone and the marks on my leg were post scabies. The ones on my tip weren’t there at the time. But over the last 2 months since I did my treatment the ones on the tip of my penis seem to come and go? Did anyone else experience the nodes going away then reinflame?
