Yes it is hard to ask questions or even know what questions to ask before one knows what the problem is or what part of the body is being effected, etc. And even then (when it is me) it oftens takes me getting my thoughts in order...I don't realize how much I don't understand until I've reflected afterwards. So I determine to ask the doctor at next opportunity, prepare a list of questions etc. Or else do some research....or ask others like Kammy has done here. Not all of us are as quick on our feet as others.
