Hello Dr. Rynne, I have a an area on my right front calf that has hard scaly area that gets hot and feverish from time to time. The area does not itch but does ooze some times.It is purple/red in color and gets darker when it s flaring. Any idea? I have several autoimmune issues, such as,Sjogren s, RA, & Fibromyalgia.LUPUS is prominent in the family, could this be some sort of Discoid Issue.
