Hi
I have a feeling that there is no magic pill, alternative or otherwise, that will treat this condition. In your research did you come across the website: www.ihrfoundation.org ? It is the best I have found with information on this condition. I do not have it myself but researched it a lot as I think that a friend may suffer from the condition but is having a great deal of difficulty in getting the Docs to take him seriously.
There are many symptoms that may be present and if neck stiffness is one that you suffer from then massage and relaxation may help as they do my friend. I also think that it may be worth while seeking out a really good acupuncturist as this maybe able to help the pain. Make sure they have a reputable qualification as in the wrong hands things could get worse. Possibly a craniosacral therapist may be able to help. They say that they can feel the flow of the CSF and therefore may be able to influence it. Worth a try?
I wish you well in your search. It is a dreadful and little known or understood condition that I would not wish on my worst enemy.
