@quickstepper I've printed this article and will read it asap. I know that doxy would not be effect against a routine virus, but it has been effective against whatever causes my rosacea ~ which to the best of my knowledge is a form of inflammation. One can even find specific forms of it on the market targeted for rosacea. Grasping at straws! (If nothing else perhaps it will clear up my current bout of rosacea.) Incidentally, I've been 'kicked out' of the LC clinic; CFS seems to be my current diagnosis. As you point out, these ailments are very similar...including the fact that they continue to plague and puzzle both patients and physicians. Thanks so much for taking the time to respond. I am most appreciative.
