As a long time CFS sufferer I sympathise as I have found it difficult to get treatment here in HK. Alot of Drs just do not understand CFS/ME at all. Two suggestions I can give.
1) Visit Dr Tim Trodd at OT&P in Wan Chai. The practice details should be listed in the A-Z. He has a good understanding of CFS.
2) Look up
Read More. Dr Myhill is a UK based GP who specialises in CFS. Her website is very informative and includes details of her treatment regimen plus also details of CFS related tests that can be run (even for non UK residents)
Hope this helps.
