I am a 53 year old man with extreme flushing and burning on face. All bloodwork and urine tests tests are good for Carcinoid and Lupus. I too have cold hand and feet. Trying to get a CT scheduled. Symptoms are getting worse and have tried everything. Old history of testicular cancer in my 20s and had craniotomy when I was 18 for a brain abcess. There is no sweating here. I am in good shape and don't smoke. Gave up beer and wine. At wits end
