What is the best way to word the following sentence?
A diagnosis(es) and remedy(s) remain elusive as we continue to seek help from various medical professionals.
Since diagnosis ends in -is, should the parenthetical plural "diagnosis(es)" be something else? I could reword but it sounds a little...wordy. Plus, if not also spelled out, "remedy(s)" then seems inconsistent:
A diagnosis (or diagnoses) and remedy(s) remain elusive as we continue to seek help from various medical professionals.
