Is throat inflammation/irritation normal for regular smokers?

I've been smoking every day for a few years, and I've always had a problem where my throat gets irritated after I smoke and it gets me paranoid. It doesn't really hurt that bad, but it aches from below my jaw down to my adam's apple. It's not a scratchy pain but a dull ache. That wouldn't bother me much but I also have a scraping/clicking sensation when I swallow, mainly after I've smoked. I'm a really skinny guy and I've read that this is a normal problem, especially in people with anxiety. I can do things like bend my neck backwards, and if I swallow then it will feel normal, so I know I'm not imagining it. These symptoms seem to be worse after I smoke but I also notice them before I smoke too, but not all the time. I'm thinking that maybe the smoke irritates my already narrow throat so it causes me to feel my epiglottis scratching the sides of my throat or something. I haven't went to the doctor about this or anything because it's not something urgent that's really painful or anything, it's just irritating and my mind wonders into all directions when I'm stoned like maybe I have a cancerous tumor growing or something. Is this something other people experience after smoking?
