Just a quick note - if you are diagnosed already, you get to see a neurologist. You won’t be sent to a general internist.
Spain is a huge country - Gitte’s experience wasn’t ours, but we live in the north. There is no problem with houses being bulldozed as most people buy old properties and do them up. Our experience has been nothing but positive, but it has been tough going.
Whatever happens - you will need to learn some Spanish. It took me about 5 years of studying at home and I was still rubbish - but after moving here, it took me a year, with the help of my lovely neighbours. My GP doesn’t speak English, so that was a quick learning curve. If you get an English national who teaches Spanish, just learn enough to get by at first. Shopping Spanish, medical Spanish, car Spanish and the local terms for stuff. It makes a massive difference.
The DMDs are supplied by qualified nurses who work for the various pharma companies.
Sorry, going on too long, but if you move to Spain, your experience will be much better if you avoid the huge developments and try to live where there are few expats.
I can’t express how much living here has saved my quality of life, but my MS is so much better here that I feel like a normal person again. I was housebound in the UK but not here. I love it to bits. I go to my neighbour’s house each day for coffee with the other neighbours. It took a year to catch up with the conversation, but since then, my life has been a delight and a joy.
