I ve got a burning sensation in the left side of my nose and a very sore throat. I had some sinus problems a week ago, and had to take amoxicillin, but I doubt this is the problem as my sinuses are fine now. I ve got exams tomorrow, and PE outdoors in the cold, so I don t know what s wrong with me or what to do. It started hurting this morning and has elevated to an unbearable sensation, and a woeful headache.
