PUNCTUATION AND CAPITALIZATION

Question

The patient has had recurring episodes of paroxysmal nocturnal dyspnea and 3 pillow orthopnea. Associated symptoms such as lightheadedness, breathlessness, and exertional dyspnea occur during daytime hours.

Is this statement correct for spelling, punctuation and capitization?
Should 3 pillow have a hyphen?

Answer 1

I would say so, yes.

... 3-pillow orthopnea.

Everything else looks fine.
