You must see a Chat Doctor. Viral illness ID self limiting with time it will settle - take paracetamol, a lot of warm to hot fluids rest is what is needed. Smoking is a predisposing factor for development of throat difficult swallowing, weight loss change in voiceOral cancer causes non-healing ulcer in mouth which can be painless also sometimes also can lead to difficulty with speech swallowing. Lung cancer is suspected if one has chronic cough with blood stained sputum, chest pain shortness of breath.
