Does social security help with the surgery costs? It does pay for time when you are unable to work. Provided you and your boss are registered and paying into the system. If not you can consider asking your boss to pay for your surgery and you can pay him/her back over time.
I am fairly certain that your employer is required by law to pay into the social security system, precisely for these types of emergency situations. If your employer hasn't been paying into the system then the labour department can compel your boss to help you out.
