My partner, on March 28th, had a fall in Tui, Spain, thought she had an ankle sprain, went to a public hospital in Pontevedra and was diagnosed with a complicated fracture. It was a public hospital, long 4 hours wait in emergency, full consult, X-rays, realignment, cast. We later at home got a bill for 480 Euros. It was money well spent as we received excellent care. I fully understand your anxiety; you are in Spain for pleasure, fun, interest and you have this realization how totally screwed you are with an injury. We had to go home NOW; money, pain time, disruption. If you do not have travel insurance, check your credit cards for coverage or other insurance that may provide a foreign travel medical/evacuation benefit. Good luck!!!
