A lawyer is good, but a doctor or someone in the medical field will also be important to consult. The terms they use will have medical and legal meanings. For instance, attending physician may not mean only your doctor. It can refer to the emergency room doc. There's loads of ways things need to be assessed before you sign. Just keep your eyes wide open.
I do have an advantage in that I am a doctorate level biochemist and medical terms aren't that much of a mystery to me; I have much more concern about lawyers and their ability to twist language and make even simple words mean something quite different depending on the lawyer's intent. I will be quite careful!
