I am experiencing flushing of face and sometimes neck and upper body. I have stage four clear-cell carcinoma, but last scans showed only one spot of cancer, that being in my thyroid, and I am taking Votrient for at least two years. I talked to the pharmacist and they said there is no history of Votrient causing flushing. When flushing I also experience fatigue and some loss of mental acuity. Could the thyroid be doing this?
