I agree that it's not particularly good practice for your instructor to be diving a computer when you don't have any gauges. It's not particularly good practice for you to dive without gauges, period.
I don't see any way that you could have presented with your symptoms before you had them, and once you had them, it was pretty clear that it wasn't DCS. With no high fever, no serious systemic symptoms, and just a rash and some pain, it's not unreasonable to wait for a scheduled physician's appointment. Not everything under the sun needs immediately evaluation.
