I have been experiencing hoarseness with no Sore throat or pain, taste of blood in throat /mouth, had episodes of blood smears in vomit and sputum, feels like a knot in throat when I swallow, and chest pain/ tightness making it uncomfortable to breath at times especially when lying down ... Almost like I can t get a deep enough breath in. This has been going on for a few weeks, the hoarseness comes n goes but has definitely made a significant difference in my voice! I have gastroparesis and reflux so it maybe associated, but sounds like cancer!! I feel like I m being a hypochondriac, do u have any insight or do I just need to go to my dr?? Thanks
