One-sided throat pain

This pain in my throat has been on-going for a whole month now. The antibiotics had not helped at all.  I think I have low grade fevers too. Am not sure what's the problem and have called up my specialist.  Apparently he is busy and can only return my call on Thursday.  

I've done some google searches on the side effects of sulfasalazine, which I take a dose of 3000mg a day.  One of the websites www.arthritisresearchuk.org has a brochure on sulfasalazine, and it is indicated that I should tell my doctor immediately if I experience any of the following while on this medication:

- a sore throat

- a fever

- any other symptom of infection 

- unexplained bruising

Right now I'm still in the dark about wht could be the issue, but I'm really looking forward to the call from my doctor.  Hopefully, he has an answer for me.
