Hi, My Name Is Peter, I When I Was Young,

Hi, my name is peter, I when I was young, I took a corrosive substance without consent, I had an explorative surgery don't on my stomach and all went well but my throat narrowed, I can't even swallow small tablets of drugs and only rely on soupy food, I keep forcing food to the throat, I have fear of another operation being done or even worsen the situation, what could have happened in my throat, any future risks?
