I'm not sure if this works internationally but it should since it's confidential and you don't need to give your health card number...
Here in Canada we have free health related information and questions answered from registered and trained nurses: 1-866-797-0000.
Telehealth Ontario. Great service.
Please update me if it works so I can spread word of this. I pay for it with my tax dollars and I would be glad to share it internationally. Health care and information should be free throughout the world.
