I have Lupus. I was put on high dose prednisone, which caused me to retain fluid to the extent that my legs were so swollen, that the pores split and fluid would run down my legs. I had severe pitting, weeping edema. Once the meds were decreased, and the swelling subsided, my inner and outer ankle area appears mottled under the skin, almost like petechiae, but in larger patches. What is this?
