I have had bronchitis and sinus drainage problems over the past month.  I have taken two round of antibiotics.  After all that i have had slight ear aches on both side and a continuous sore throat.  Everything with the cough and the drainage is much much better.  But the sore throat is persistent.
Hello! I have been through your question. Related your concern you should know that if you have persistent throat pain, your body could be trying to tell you that something is wrong. Many common colds and viruses can cause a sore throat, which typically resolves within a few days. But when a sore throat persists, and you can't find relief and after two antibiotics treatment as you have, It's something to be taken seriously. Some possible causes of a chronic sore throat include infection of the tonsils, strep throat, allergies, mononucleosis, inhaling air pollutants, smoking ore inhaling through the mouth instead of the nose. To successfully treat a sore throat, you have to know what is causing it. What I suggest for you is doing a physical examination by an ENT doctor to see in detail the local situation of your throat and ears, full blood count and throat culture test to do a differential diagnosis between some the most probably of above-mentioned causes (non-treated well tonsillitis or strep throat, mononucleosis and allergies). I hope my answer help you. I wish a quick recovery.
