What Causes Bruising Along With Itching All Over The Body?

I have severe unrelentless itching of my skin. It lasts all day now --- on my back, my arms, my neck, my abdomen, my head, my legs --- all over! I also have unexplained bruising on various parts of my body. Right now I have a very purplish area on my abdomen. My primary doctor is on vacation and I can t get appt. with a dermatologist for 2 weeks. I also have moderate to severe fatigue. I am getting very concerned. Should I go to Urgent Care.
