There is a really good place called Spineworks (previously The Spinal Joint) on 10th floor Empire Soho Subang. I've been seen by both Dr. Barry and Dr. Jennyfer. While they are both excellent, because Dr. Barry is always booked full he doesn't spend as much time and detail as Dr. Jennyfer. If I am not wrong, first visit is RM120 and subsequent visits RM100. I used to have a lot of back problems but they've done some miracle work, especially Dr. Jennyfer. Highly recommended!

Sorry, can't help you there. Neck cracking especially is a risky thing, one wrong move and you could be done for life so I'd rather stick to the one I know for sure is good and safe. There might be others who are able to help you. Good luck
