I am having trouble with swelling in my face. This has been happening every 2-6 days. It is never in the same place or on the same side. I can feel it starting and have been taking allergy pills (I have never had problems with allergys before). I also keep ice on the affected area. It usually goes away between 5-24 hours. I had colon cancer three years ago (stage 2A) and had a resection but opted to do chemo or radiation. I am 65.
