Don, he is doing the correct thing. Suppressing the night sweats would be foolish. THe the night, the liver and kidneys are very actively engaged in detoxifying and eliminating old toxic waste broken down through the inflammatory process in the lungs. However, parts of the waste ends up the lymph and blood and enters the muscles and joints (aching). The next best option to deal with this situation is to remove the waste via the swaet glands of the skin. To get the toxins out of the blood is bringing him great relief. If suppressed, it could lead to serious damage of the immune system and eliminative organs, and set him up for a repeat pneumonia at a lter stage. To support the body in its effort, he would greatly benefit from keeping his colon open and clean through colonics, colemas, or at least, water-based enemas. Lung problems are always caused by disturbed colon functions, most of which is, in turn, caused by liver bile duct congestion. Once he has recovered, the liver cleanse/colon cleanse regimen would be a good idea for him, to improve his digestive and immune functions (see The Amazing Liver Cleanse, ener-chi.com, for details.
Pneumonia is also related to the release of old grief. When there are emotional flash backs at the time of breaking down and releasing old toxic waste from the lungs, this actually clears the old emotional trauma behind the congestion. He is doing this right now.
