10 months ago I got sick working at a snowpark and my body hasn't been the same since. I lost a lot of weight and my appetite has never been very strong since then. Every morning I wake up with my stomach hurting and later on in the day my stomach will hurt for hours or minutes at random. I got blood tests and stool tests done at a hospital and they said they didn't find anything. After some bad diarrhea today I passed what looks to be two parasites in my stool. I've gotten these a lot and would like to know if anyone has any idea what these things are and how I could get rid of them. Thanks.
