When I swallow I feel something stuck in my throat as if it’s a piece of food or something, why is that? ?

So yesterday it started and when I swallow I can feel something in my throat like a piece of food, I am able to drink water and eat too. But luckily after sometime it disappears, I can still feel it in my throat even when i keep my head straight looking forward. I try to chew my food as much as possible and eat slowly too. But even after  I chew my food and eat slowly I still feel it, it happens right after I had my meals. When I touch my throat I can feel it as well. I can poop and pee normally. I can also talk too! Both of my legs are weak.
