I couldn't understand what she was talking about until she told me to look at my knuckles. They looked bruised. I became very concerned and went to my doctor that same day. He checked out my hands and came to a quick possible diagnosis of Lupus. I'd never heard that term before, so he explained it to me.
Lupus attacks the body and organs eventually.
There is not a good prognosis for Lupus patients. Basically, the black in the knuckles looked like a frostbite effect. He ordered bloodwork, and I made an appointment to go back for the results. There is a test for Lupus, and thank the good Lord, my test came back negative. However while I was waiting for my results, the black went away but I started experiencing tingling and numbness in my hands and feet.
