Yes, welcome to the forum. I'm with Babs on this one too. I don't have a lot of experience with discoid lupus, however I do have the purple "livido reticularis" on my wrist and ankle. It's a sign of vasculitis too. It comes and goes with the severity of my lupus.
All I can say is that discoid lupus will present itself as unique as systemic lupus will. Everyone is a little bit different in their symptoms. I would stay the course and use the cream your doctor gave you. If this new spot gets bigger, I'd go in for another visit with them.
I can do anything through Jesus Christ who strengthens me. I have learned in whatever state I am in, to be content. Phillipians 4:11-13
