Globus/stuck in the throat feeling followed by swollen lymph nodes, should I be worried?

So I've recently developed a stuck in my throat feeling that has persisted for 3 or 4 days then recent became worse ending up with a slightly swollen lymph node and a different discomfort on one side of my throat. However I otherwise feel fine and have just been dry coughing occasionally due to the irritation.

To tell you how it started and in the interest of being completely honest it originally developed after a time when I smoked a joint with extremely dry tobacco which was essentially dust, which I ended up breathing in a some of. After this I coughed a LOT and after was the first experienced the globus sensation, it wasn't that bad however and seemed to get slowly better over a couple of days. Well it suddenly seemed to take a turn today as after a day where it was particularly irritating (the worst it had been) it suddenly changed and as I said previously became a weird feeling when I swallow on one side of my throat and a slightly swollen lymph node.

How worried should I be about this? With the tobacco involved and with the search results you get from this as you might imagine its got me worried about cancer... Do I need to get to a hospital?

To add a little more context I’m a 26 year old heavy marijuana user who has been for maybe 8 years. However i don’t smoke tobacco other than in a joint and even then its very little, with 30 grams likely to last me several months (hence the dry tobacco).

how are you feeling? i came down with this 2 Months ago after having a dry cough and hoarseness and my voice. This came out of nowhere. Let me know if you had any luck. Hope you’re feeling better

wow i didn’t see cancer involved with this.
