The more I think about it, I realize that it is getting more and more impossible to heal in this polluted world. What were once relatively simple rare problems are now chronic and intractable.
In part I have to agree with the idea that it is getting more difficult to heal in today's polluted world, unhealthy diets and unhealthy lifestyles. However, I am still the eternal optimist and think that nature still has the answer in most instances and in many cases, perhaps even one that has been as difficult as yours, it is simply a matter of not yet having found the right combination of the things nature has to offer.
Don't give up - I am consulting and researching and may have some encouraging suggestions for you soon. Bear with me - I am still a bit limited in how much time I can comfortably sit at the computer thanks to my own physical issues (compressed discs/sciatica mainly), but I am getting better all the time and finding the right combinations for my own issues. Also, one of the main people I want to discuss your problems with is out of pocket right now. I will be visiting with him personally in about a week and a half though. I did speak with him briefly and he told me that he will have some suggestions. He is an extremely qualified man who I will be introducing to this forum and to CZ soon - having served for decades as an MD who converted slowly but surely to integrative and naturopathic modalities because he wanted to truly heal people and not just manage symptoms with drugs and procedures that led to further problems.
