Discomfort in stomach area after forced vomiting

28M, 170cm, Obesity

Hello, first of all I did something bad to my body and I regret it

I was eating something, it’s a rice, a non healthy one and I decide to throw up just a couple mins after I finish eating it, I think its 5mins.

So my stomach is not full at that time, its empty and the food just in, I throw up, and I notice I didnt throw up all, but I was forcing it, cuz I wanna throw it all out, then I give up. But I feel a contraction in my stomach.

But immediately after I throw up, I feel pain on my lower back and my side.

Then, right after, I feel a discomfort in my stoamach, and whenever I eat something, I feel a distention in my body. and I feel better when I belch. So I think I might have bloating. But whenever I eat something. I feel something in my stomach. It’s like the food is slowly move or maybe stuck. I don’t knoww. Can I know what is this and can I fix it? It’'s 4 days already
