Thais are generally quite helpful, so you should get assistance from locals if you need it. The Tourist Police will help you in case of a robbery or rip-off. The Tourist Police hotline is 1155.
Many hotels can refer you to an English-speaking doctor. Major cities in Thailand have some of Southeast Asia's best hospitals, and the country is quickly becoming a "medical holiday" destination (i.e., a cost-effective place to have plastic surgery, dental work). However, if you are still wary about treating serious health problems in Thailand, you can fly cheaply to Singapore for the best medical care in the region.
Most nations maintain diplomatic relations with Thailand and have embassies in Bangkok; a few have consulates also in Chiang Mai.
