Pharyngitis

I seem to have it again.  I am on Biaxin 500mg 2xday and the doxyi 2 x aday 100mg.  I've read that it could be fungal so I'm going to take 200mg of diflucan a day and see if that helps.  I also went back on the thrush losenges?  Hard to swallow and feels like something is stuck in my throat but it's just red, no infection I can see.  Has anyone here had this a lot and what did you do for it?   Did it resolve on its own?  I just can't see adding another antibiotic.  That would make 3 different ones a day plus all the other stuff I'm on.
