i went to a parasitologist to test for parasites. nothing. my main symptom is constipation, but not the "can't go for x number of days" kind. it's the kind where everyday i go a little, but there's a lot stuck somewhere in my tummy, maybe sigmoid colon? lots of gas, bloating, and if i eat insoluble fiber it irritates my gut so i end up with a strong urge to go, but in the end all i get is a lot of gas a little bit of crap shooting out. i get this horrible stuck feeling afterwards too. so nauseating. it's debilitating and makes it hard to concentrate. what are your symptoms?
