I've had a chest pain for nearly 4 months now, and a feeling like I want to cough which I never do. Two weeks ago, I had a sore throat which has refused to go even after doctor gave me antibiotics. It's so depressing feeling a lump on my throat everyday. Sometimes, the pain gets worse when I lie down and I have difficulty swallowing. Then, I get a dry cough. What is the matter with me? Please somebody help!
