Hi Louise - welcome to allnurses

Kudos on using your experiences to help friends navigate the intimidating and overwhelming landscape of medical care and advice.
What kind of information is that you're looking for? I assume that by "I don't know the appropriate manner to present a patient" you mean here - the kind of information that would be helpful is age, gender, medical history, symptoms...
People here will generally be cautious offering diagnoses, but are very helpful with suggestions and information sources. Good luck!
