Cyst or something sinister? Please gu!

The image i am attaching is the cyst or something like that just in between the tongue's back part and the epiglottis. I had posted a free query in the ENT section one doctor mentioned vallecular cyst. The closest similar pictures i could come across was epiglottic cyst on google. They look pretty similar to this. So i had observed this thing since last year or many months you csn say. Hx: I have history of allergies, recurrent throat infections and also tonsillitis since childhood. Recently had a bad chest infection, sfter a throat infection. After that the cough has reduced a lot but sometimes i get tickling issue in my lower throat, not sure if its cuz of this. And i dont smoke or eat tobacco. I rarely drink thst too in moderation. Never had choking symptoms or any apnea. Please guide me doctors, i am extremely scared. I am 27M, fairly active. Only symptom is occasional throat tickling or irritation mostly after eating food. But i would not call it as sore throat. Please gu
