I don't have any suggestions to offer, but I wanted to tell you how badly I felt for the problems you're having. It must be really tough. We've been fortunate that my daughter's health has always been excellent and she rarely gets sick. About the echinacea... I recently used that when I got real sick and it seemed to work miracles almost overnight. My mom used it too and said the same. I questioned the woman at the health food store about using it for my daughter with CAH, thinking she might get sick too because the rest of the household was. She thought it would be perfectly safe to use (although in the end she didn't need it because she was the only one in the family who didn't get sick). The kind I used was an echinacea/goldenseal extract and it was VERY bitter and horrible tasting. My son mixed it with soda because that was the only way he could tolerate the taste. But it did work excellent. I went to bed at night feeling like I would die, and woke up in the morning feeling great. I still had a cough, but I felt SOOOO much better. I continued taking it and got better rather quickly. My daughter has been to Children's Hospital in Boston. That's where she went to see her surgeon/urologist (Dr. David Diamond). She won't be going back there for a long time... which is good, it's a pretty long drive for us. We live out near Springfield. Good luck with your son. Keep in touch and let us know how things go.
