It would depend on what you have. Hope the doc takes a swab.
A persistent cough and sore throat could also be caused by post nasal drip or even reflux, allergies, etc..
I would say it would be best for you to maybe be sent to an ENT if he's not thinking it's strep.
For strep, your best bet is antibiotics....I use Zithromax with no problems...but I've not had c.diff...
If you're not on any probiotics....please consider to use them regardless, and especially if you're put on antibiotics.
Keep us updated as to the outcome.

My doc's logic.. "TREAT (FROM)BOTH ENDS" worth it !!!
