I am experiencing localized itching on my left breast and on my upper back. Both areas are covered with tiny bumps and sores (probably irritated from scratching). The itching has traveled from my right breast to the left and from my lower back to my upper back. I also have a quarter size area on my knee that is red and scaly. The total time for all of these symptoms is approximately four weeks. I have been diagnosed with Lupus since 2013, however I ve had very minor symptoms and no skin outbreaks since that time.
