This same problem happened to me last year, and persisted for about a week before it disappeared. Currently, this problem has been on going for 4 days now.
Imo, there seems to be some kind of blockage in my intestine or stomach b/c whenever I eat or drink something, even very little, my stomach gets very full and bloated. I haven't taken a soild poop in a few days, its just liquidy or a very skinny poop, loosely clumped together and mucousy; not a big regular one like i'm used to. From looking at my poop (very light in color) it looks like my food is not getting properly digested. My lower abdomen gets very bloated and full of gas. My lower back started hurting me b/c of this bloating. I have very smelly gas as well.
I am a very healthy person and gets plenty of fiber and drink lots of water and usually go to the bathroom 3 times per day on a regular basis. This all started happening after a night that I got really drunk and the next day I didn't go to the bathroom or eat much.
I have been taking a psyllium husk supplement to try to flush out whatever is in there, but I there is still something wrong. I just filled clogged up, not constipated, but clogged up in my intestine or something. I also resorted to giving myself an enema but this did nothing besides flush some poop out.
What is wrong with me?? Your help is extremely appreciated. I am happy to answer any of your questions. I am an avid body builder and this is inhibiting me from my proper diet. Thanks!!
