Hi Ekri. I've not had the redness in my face, neck or chest. Well, not quite fact, one evening my husband asked me if I had a fever because he said I was flushed. He took my temp, but, no fever. That was only the once and it was just my face. But the heat and prickly sensation goes on for hours . Thankfully, if it happens at night, by the morning it's dissipated. One of my oncologist checked to see if I had a "functioning" nets, and, the blood tests came back as it not being "functioning". I guess time will tell, though, I see the thoracic surgeon next week and hopefully surgery to remove tumour in June. Hoping for a "one and done" .
