Hi, I have a sore throat which began 9 days ago. On the second and third day I also had tenderness in my neck. Maybe swollen glands? I began having symptoms in my sinuses also. I was seen at the urgent care at my PVP office. There they did a quick strep and it was negative. I was told I have an upper respiratory infection. A few days later I followed up with my PCP because my throat was really hurting. I ve never had a sore throat this bad that I can recall. My symptoms at this point were sore throat which hurts to swallow saliva and also when sticking my tongue out. A productive cough a night laying down and in the morning that brought up yellowish green sputum. I thought a sinus infection with post nasal drip? My PCP did not do another strep test. She listened to my lungs which were clear. Sent me for a chest xray to see if I have pneumonia, but the xray was clear, no pneumonia. She prescribed doxycycline for bronchitis. That was two days ago. I have not started the antibiotic yet because I have to avoid sunlight and I had planned outings with my kids. My sinus are feeling better. I think there is still post nasal drip, but mild. I didn t cough up as much this morning as I have been. However, my throat is killing me! What could be causing this?
