Both these doctors are knowledgeable in the condition, but they do approach it differently. My understanding from taking patients that have previously dealt with them is that Dr Lam is very adverse to the use of hydro-cortisone, adrenal extracts and herbs, whereas Dr Wilson is a staunch advocate of using extracts. In any case, this only comes from the limited information I get from dealing with former patients of theirs and reading some of their articles - no doubt this does not provide a full picture of their treatment protocol, as would just a sample of my own articles.
I would speak to/email both, and trust your instinct. Hope that helps.
