痛症治療中心需要申請牌照

Unable to answer due to lack of information.

The license/registration you will need depends on the detail of operation.

For example, if this treatment center uses massage as the primary treatment option, a massage parlor license from the police will be needed.

If you use some special equipment, additional license may be required.

In short - there is no single license/registration for such purpose.

係香港打開門做生意梗係要領牌喇，最起碼要有商業登記牌照，其他再根據生意的類別再申領相關行業的牌照，如做飲食的要向食環署領牌，賣石油氣向消防處領牌等等。
