It will be better if I can get the list of hospitals with endocrinologist ,so that I can directly visit them.
Thanks all for your valuable help!
Try calling the automated appointment booking service the HA has, it will give you some clinic options and date ranges to choose from.
The quality of the referral letter is important. The typically poor letter gets you consigned to the 'routine' queue. In the end, your condition may simply be 'non-urgent' and 'routine'. If you want to be seen earlier then you need to go private. Getting a private consultation with a specialist (in the thousands of HKD) will hopefully get you a decent assessment of your condition and how you should proceed, you can then decide whether to wait for public care or continue with private care. The private clinics at the University hospitals may be less 'money orientated' than the others, but there's no guarantee. You get greedy doctors too, like those selling 'exemption certificates'.
