I'm not on the med merry-go-round because I'm allergic to most of them, and I had cortisone so much when young, they are saving it for life-death issue. My immune system was never normal... being allergic to everything but clean air, pure water and cotton. (well, I wouldn't let them test me for cotton because I love it so and it feels so good.) They wondered how I lived without being in a bubble. I had state of the art allergy treatments in the 80s, which literally saved my life. I do see, as I age, some of the allergies creeping back in, and a few (mainly food items, and molds) are quite severe.
I had a good friend in the late 60s that had SLE.
