If you need directions, I can PM them to you.
I haven't done acupuncture in Hong Kong--but I did in Mainland China when I lived there. There are many acupuncturists around, though. It might be best to ask for recommendations on specific acupuncturists on this forum.
For massages, it really depends on what type of massage you'd like. Do you like Thai, Swedish, Chinese style? I've tried a few places and the one I like the best in Hong Kong is called Thai Comfort. The branch I go to is in Yuen Long, though because that's near where live. I have searched for a website for them but all I have is a phone number: Tel:2443 0068.
I'm not sure what part of Hong Kong that you're in--that may determine where you go for massage. You might request other recommendations on this forum for massage places that are safe, clean and reasonably priced--there are quite a few out there.
I hope you feel better!
