I had a red oval spot (about the size of a silver dollar) on my left rib area for about 1.5 weeks. it did not itch, and was shiny like scar tissue. the discoloration is still there (though less intensely colored) but has been joined by red raised hives, which have been there now for about 2 weeks (on top of the initial spot, bringing total rash time to almost a month). most of the time none of it itches, but the hives are sore and I don t know what s causing them or how to make them go away. I haven t recently switched detergents, meds, etc, so I m very confused as to why the hives are lingering.
