I know how easy it is to hurt people on this site, so I'll tread lightly. I'm not sure how you were made fun of, and it would indeed be reprehensible. I support you in reporting it.

I may be misunderstanding your post; however, try to be cognizant of the fact that "complaint" or "chief complaint" or "presenting complaint" are all shorthand that medical people use to refer to the primary reason a person presents for care; in fact, a "CC" is typically the first category in a standard medical record, followed by the HPI (History of Present Illness), PMH (Past Medical History), FH (Family History), then the PE (Physical Examination), followed by LD (Laboratory Data), etc. I've always felt that "complaint" was an unfortunate choice of terms, implying that a patient is whining, not trustworthy, and begging for sympathy. CC is a only a subjective statement; e.g., "The patient complains of chest pain," and the following objective portions of the record may demonstrate a heart attack, or a broken rib, or any number of conditions. It sounds demeaning but isn't meant to be. You can even Google "chief complaint" to see its meaning.

When I've read my own medical records, "complaint" makes it look like there's no basis in fact; however, a chief complaint of "back pain" means that this is my subjective experience; it may be shown on radiologic studies that I have a ruptured disk, or it may be pain that originates in my gallbladder, etc. It doesn't mean that my complaint of back pain is any less legitimate or that the doctor questions my judgment.

An ER doctor might ask, "What brings you to the Emergency Department today?" "I'm depressed," I might answer. S/he writes "Chief Complaint: The patient says she's depressed."

You probably already know the above, and I might not have understood how the healthcare worker embarrassed or upset you. Hospitals seem motivated these days to ensure that patient experiences are positive, and I hope you get some resolution.
