I Have Lupus, Connective Tissue Disorder, Sjorgens Syndrome. I Developed

I have lupus, connective tissue disorder, sjorgens syndrome. I developed 2 spots above my pubic hair. They both came up suddenly, 2 weeks ago. They are 6 inches away from each other. The first is red and 3 days ago, a deep purple vain went in direction of the vein and 2 nights ago, the sore bled under the skin. The blood is fading, but the huge vein is still large popped out and red area. The second spot is same size and Wednesday night, just opened up with a white puss and blood. I went to my pcp and they took a culture of the pus. It is still draining with blood and pus. I am scared that with my low immune system it could become septic. I have it covered with a band aid with anitbiotic cream. Lupus related or possibly a skin problem?
