I've been treated with Pred. for about 20 months. Have, both, GCA and PMR. Lots of ups and downs due to Flares. Five days ago, I was given a Boost and put back up to 60 mg. Had been on 30. In the evening ( usually after Happy Hour ) but only sometimes, my face becomes very flushed and slightly swollen for several hours. It's only on the right side. My BP is up during that time, too. This had happened a few times months ago but have never figured it out. Just curious....anyone else have this reaction/side effect ?
