I have some small white lumps at the back of my throat, I had fever and consulted a doctor and fever was gone and throat pain decreased after medications but a week later the white lumps returned with some ear pain which again healed after same midications ....it has been 3 weeks now the lumps are again returning and right now I do not have much pain while swallowing but slight cough ..... can I be sure it's just due to weather change and not anything else???
