Newly Diagnosed And Want To Know What Is And Isn’t Related To The AS?

I’ve read through several Q&A and don’t see info on some of my abnormalities. Anyone have easy or unexplained bruises all over you? Extreme sensitivity to tempatures? When feet are swollen they turn purple-redish color? My SI joints hurt but recently while I’m trying to exercise or sit my tailbone hurts, anyone else? Just trying to assure myself my rheumotogist is on the right track. Thank you
