I had pneumonia about 3 1/2 weeks ago and am just now starting to feel better BUT I am still experiencing lots of sweating! I'm not on Biaxin but a lot of prednisone. I don't know if it's the infection or medication but I can relate! Hope you fe http://www.medications.com/effect/view/21582?item=693
