Hi Margo,
I live on Arenal Golf, but also read your forum as of course we have been experiencing the same problems as yourselves over in Duquesa.
Re Health emergencies, there is an emergency operator on 112 who can put you in touch with an English speaking operator. You can use this number across Europe I believe. The Andalusian Health Service has a number much like the UK NHS Direct which gives you access to information in around 10 different languages. The number is 902 505 060.
Provided you have an E111 from The Department of Work and Pensions you can seek help from any Health Centre or Urgencias. Urgencias are a bit like a more local version of a hospital Accident and Emergency Department. It's useful to take a photocopy of the numbers side of the E111 card and a photocopy of your passport along with you to the Health Centre or Urgencias. Our Health Centre has a volunteer English speaking interpreter present for 3 hours each morniing.
Health care here is excellent. There is no overall prescription charge, but your medication will cost about 33% of the actual cost. This morning I took four prescriptions into the Farmacia ,including one for an antibiotic, and the total cost for all four was 11 euros.
Hope this info is useful.
Jenny
