I have had itching at night so severe that I have had to sleep with an icepack. It is not always in the same spot. There is no visible rash, and this has been going on for 6 weeks. I did have a fungal infection 2 weeks ago on my belly, but that has cleared up with a cream. I have had a low grade fever at times. I know I should have some blood work, but I don't have an appointment for a few weeks. I am concerned about an autoimmune disorder.
