One of my tonsils is swollen

Was vaping and one of my tonsils are swollen the tonsils was big before I wash my mouth wit salt water I had a feeling where there was something blocked down my throat it was hard for me to swallow so I quit. I went back to vaping everything was fine until I bought the vape from the gas station I worked at could I be allergic to what’s in the vape I’m going just stop vaping but I’m worried it’s something serious. I haven’t vape that long maybe 5 months but back on my tonsils are white but that’s because of the vape have u guys heard of this? Btw it got smaller this was after me using salt water it was bigger then this
