Why do I bloat so bad after walking???

Ok-I've solved the spare tire issue yesterday---I'm so bloated now that it doesn't move as much as when I'm not so "puffy". I'm more firm-because I'm so bloated!!!! Now I have support for my spare tire....when I walk I bloat. I'm even a pound heavier than yesterday. I've gotten to realize--after a day that I do "walking" I need to take a day off so I can "drain" and reduce my size back to normal........ug
