I am 42 year old male, I've have been having green stools over the past couple weeks along with lower abnominal pain all the way across my waist line, and sometimes just below my right side rib cage, last night when i pushed on my stomach just above my navel it produced a very sharp pain, I havent been eating any vegitables or food containing food coloring, and in the evenings i tend to run a fever. Could I get some advice!!!!!!
