Two weeks ago I started Arimadex .5/wk. At same time I started prednisone and albuteral for pneumonia. I am no longer on prednisone or albuteral. But my body feels like a large truck ran me over. It's like HIT leg training x10. When training I feel like I could cramp up with each rep. Does any of this sound like side effects or sensitivity/overdoes to anastrozole? What do guys mean when they say anastrozole crashed E?
