So I am looking for a reliable source of medical terms in Spanish. I know enough to get by with limited casual talk but am looking to be able to perform a medical assessment with non English speakers. Any advice?

All of the books I have found seem to have terrible translations. They at least receive a laugh from patients when I try though...

Thank you for your work. Watership Down has been in my life since I was a kid, is part of our family, and was one of the first books that truly developed my interest in reading. Do you have any books or authors that have had the same influence?
