I have been sick for 2 weeks, it started with just symptoms of a cold, stuffy nose coughing, the usual. But then I started to get stomach pains brought on by standing and walking, and about a week in my stool became pretty much just liquid and has gone from brown to green back to brown in the last week. All of the cold symptoms are now gone and The stomach pain has subsided a couple days after the stool began but that problem is still going on
