If you have any medical issue during the night and you are not sure what to do, call 19222. This is a regional emergency number for this area. After describing the problem, they will either send you an ambulance, tell you which hospital to go to, or send an on-call doctor to your house.
In general, medical care in Germany is very good, but hospitals may not be as new and up to date as we might expect. However, prices for emergency care and ambulance fees are considerably lower than the U.S. The reputation of the emergency room in Burghausen is not positive and you may want to research other hospitals in order to be prepared. If you have the option, you may want to travel to Munich or another larger city for non-emergency hospital care (the university clinic in Munich is excellent).
