Hi.
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain there is an infection in throat leading to
Pharyngitis and Uvulitis and can be caused by bacteria or virus but pus formation is commonly seen in bacterial infection..
Canker sores can occur as a side effect of certain medicine that you are taking, although at times they can be evident without any underlying cause..
You should take
Azithromycin 500mg once a day,
Ibuprofen 400mg thrice a day,Chewable
vitamin C tablet once a day, all for 5 days..
Do warm saline gargles and take throat lozenges for soothing the throat..
Avoid spicy food..
For apthous ulcers apply a numbing gel like Oragel and a steroid paste like Kenalog in orabase for relief from pain..
Take a
multivitamin tablet for 15 days..
Hope this information helps..
