What Causes Developing Itchy Skin Rash On Back Of Left Upper Arm?

Hi. 2 weeks ago I developed a skin rash. I went to another state for the weekend to see my adult son graduate. When I returned, I had a rash on the back of my left upper arm within 24 hours. I noticed a similar rash on the other side shortly after. It has spread and altered appearance as it spread. It itches, but not unbearably. It feels better when I am in bed at night. I finally saw a nurse practitioner who said it is either contact dermatitis or scabies. If I haven t been sexually active in years, live alone with not kids or pets, and no one I know has a rash, how could it be scabies?
