I have a growing lump in my throat, back in May 2011 it was checked for cancer and came back negative, since then i have had more soar throats then my combined life and can not stop coughing.  it hurts when i lay down i feel like i am being choked and it is hard for me to eat  i feel i have to fight with this lump to move over and make room for the food.  not sure if it is related but this morning i was dizzy and black-out for 1.5 minutes.
Hello and welcome to Chat Doctor, A lump in the throat can be inflammatory, or neoplastic. Polyps are common lesions in the throat. Since, the lesion is causing difficulty in swallowing and breathing, it is necessary to excise the lesion. Before excision of the lesion, an imaging study of the throat is required to assess the site and extent of the lesion. Before excision of the lesion, biopsy of the lesion is required. Thus, consult your ENT specialist for clinical assessment and management. Thanks and take care Chat Doctor.
