HI! Thanks for writing! You know, some of my bumps are little red ones too! The two dermatologists that I saw never really said what the bumps/sores were/are. They have a shiny top when they are healing too. They aren't purple tho. They are very annoying! The newest one, on my right leg, started as a red bump. I thought it was a mosquito bite. I scratched it and some sticky stuff ran out of it and dried up leaving a little pockmark.
I'm going to search lichen planus and see what I come up with. And what does precursor mean??
