Can i use diflucan and miconzale nitrate at the same time? i was prescribed diflucan from a dr for yeast infection but am having constant burning inside my vagina?

There really is no point in using both medications. The miconazole will do nothing for burning or local irritation that the oral fluconazole (Diflucan) won't do. You might ask your doctor whether a corticosteroid cream might help the local burning. In any case, that symptoms will clear up within 2-3 days of taking the fluconazole. Discuss with your doctor if you remain concerned.
