I recently had an endoscopy of my throat . The same day of the procedure, I came down with the flu and had a progressively worse cough. Lots of pain, burning, painful swallowing , no eating for about 3 days. I am better, but still have a bad cough that has now caused a lump, about the size of a golf ball, under my jaw. It hurts and almost feels like I pulled my toungue. Is this possible? Did I pull my toungue during coughing and will this lump go away? It looks terrible. Thank you, Brandi Rocha
