For the last few days I have felt like there is something stuck in my windpipe, it's not painful or anything, the only thing that's painful is it's like a burning sensation in my neck,I have also  had a really bad cough for a few months and when I cough am sure I can taste blood  or a metallic taste in my mouth my doctor is sending me for bloods as I have a thyroid problem she said if that comes back fine she's going to refer me to see a neck and throat specialist, am so worried that it could be something more serious, I guess it's not helping goggling things
