Hi, I just wanted to ask everyone if what I currently have is something I need to get checked out or if I’m overreacting. So I’m an 18 year old male and I smoke. Recently I have had a feeling of sort of what feels like a lump in the back of my throat (it’s weird to explain since I’ve never felt anything like it but that’s the best way I can describe it). I tend to worry a lot about small things so I decided to  search up what I was feeling online (I know that’s not always the best idea) and the only other symptom I’ve really been suffering with is fatigue and sometimes wheezing when breathing (not often at all for the wheezing though). As I said I do tend to worry but I just wanted to make sure wether this is something I should get checked out as I know if it is anything like cancer it’s always best to act quickly, like I said I could just be overthinking it though so any advice would be much appreciated.

Thanks.
