Since this is a yoga board (not a run-of-the-mill social community) I'd like to point out the following:
For some people a diagnosis from a allopathic practitioner is very helpful and therefore appropriate (for them). However this is not the case for all. Some folks can live with their malady but not their diagnosis. Pictures and a doctor's statement do not help them at all. Here's why.
The mind is so incredibly powerful (and we have only scratched the surface of that power). A thought placed in just such a way can be manifested. Some people, when told they'll never walk again, get up and battle and do walk, while others are debilitated from the words and accept that pronouncement as "truth". And so from the perspective of yoga it is absolutely critical that we speak mindfully to others knowing our words can manifest.
Tell a student they are well and they may be or become well. Tell them that they have high blood pressure and anxiety and they might manifest that.
I'm simply suggesting two things. Mindful words especially to those with therapeutic issue and no presumption that everyone runs to an allopathic physician whenever their throat is sore.
Of course working closely with your healthcare practitioner of choice is very important when you've determined that to be a necessary course of action (so I am not suggesting one forget or ignore that which comes up for attention).
