Oh my gosh. I'm so sorry to hear this but I'm so happy to know I'm not the only one. I've had this for over a year and have been to the dermatologist multiple times who has told me a little to nothing about it although he has shown a lot of concern but I have been diagnosed with m monoclonal protein disease. I believe it's mainly affecting my kidneys right now but I do have the hives and itchiness on my scalp and neck and upper shoulders. It drives me crazy. In the beginning I thought I might have lice because it felt like something was moving but it was my nerves.
