hi buggie, Sorry to hear about your latest AS monster rearing its ugly head. And Ive been wondering how you are. Havent been on much. I still havent been dxed but almost given up trying. I have breathing problems but they always say its from smoking. But I have just found out I have sleep apnea and were cpap but hate it. I breath really shallow and feel alot of it is because my ribcage is fused so bad. One of those indicaters the docs say I have but hey no AS for me. I just got my other knee replaced and doc is talkin about back surgery. Last september I had 3 tumors removed from my sinuses, thank GOD it was not cancer. But the tumors grew into bones so the 16th of next month I have to have bones scraped to see if it keeps them away, otherwise they will keep growing. But at least in knowing what the problem is with your lungs maybe they wont keep deteriorating with the rite treatment. Well as usual I go on and on. Take care, Connie
