Weird throat, bitter taste and tongue sensation

Since January ive had a strange sensation in my throat, initially it started like the base of my tongue, throat was itchy, very odd, just thought it was a virus, fast forward 9 weeks, ive had a swab, antibiotics and was referred to ENT, they looked in my throat and did a tube down my nose and was quite dismissive as to why I was referred as its clearly not cancer. This is all left sided, ive got intermittent swollen tongue, numbness throughout the left side, weird ache under my tongue like where tje salivary glands are. Ive noticed that under my left tonsil looks like a weird bubbly growth, ENT didnt seem too bothered. Its literally affecting my life. My dental health is good and im due to go there next week. I seriously have no idea, its just the left side of my mouth. Anyone had anything similar
