See your doctor. You may have any one of numerous sources of gastroenteritis, or perhaps even hepatitis. Diagnosing this is not reasonable on the internet. You should be seen and may need some testing, in addition to a detailed history and physical exam.
GI symptoms. You very likely have a bacterial infection or even a parasite of some sort. If your symptoms continue i would recommend seeing your pcp and having a stool evaluation completed. Best way to find the cause.
