I went for an X-Ray and found out I have a faecal overload?

Hey. I have been experiencing serve constipation for a few months now. I went for an X-Ray and found out I have a faecal overload. I just have really bad bloating and excessive gas that has a really bad odor. I have on and off acid reflux as well. Just recently I started experiencing some really bad cramping. It feels like hunger but I’m not hungry. Eating helps the pain for a bit but it doesn’t take it away. I don’t know what’s wrong with me…
