Hi, the palms of my hands appear mottled red and white. It only started occuring a few months ago. It seems to happen randomly, but is most noticeable when my hands are hanging by my waist or when I am gripping something. The blotching goes away naturally after a few minutes, or if I elevate my hands. I have been tested for SLE, RA and liver tests but nothing has shown. I have also recently started to get urticaria on my chest and neck that appear from nowhere, and disappear within 10-30 minutes. They generally do not itch, and are not raised like normal urticaria but my Dr. has stated it is urticaria. Again, nothing has shown up and tests. I am looking for a second opinion on both of these. Thanks
