Hi Megan,
NSD would be hard to continue there. English is quite limited (so explaining your situation would take a lot of effort). I suppose you could write them ahead of time with your needs. Another option would be to rent a vacation apartment where you could do your own cooking (they do have some in town)and get treated as an "out-patient" , which is a possibility. The stores there seemed to be fairly well-stocked.
The other treatments: physiotherapy everyday, electrical current treatments, some kind of sound-wave treatment (for my hips), sonic-wave treatment (for my neck and ankles), they also have you do aqua aerobics (I always skipped those sessions--a little too depressing exercising with a bunch of 90 year-olds...) and lots of hiking. There is also a salt cave you can hang out in (something to do with negative ions). that's all I can remember now--they keep you busy those 3 weeks! If I think of anything else I did, I'll write again.
