I am a 36y/o Hispanic male, 6’2, 255lbs. I have HCV, asthma and chronic bronchitis. For the past 4 days I have had bad upper and lower GI cramps followed by a semi-soft bowel movement. The bowel movements occur approx 6-8 times daily. They first started off a normal yellowish-brown then turned a dark green color starting yesterday late afternoon. I did take some bismuth tablets but it’s just a temporary relief. Today I began to feel more nauseated and fatigued than usual. My body feels hot even though it’s cool to warm outside and I have the a/c running when in my truck, but I don’t have the chills. Could this possibly be a viral infection or bacterial? I have leftover sulfa antibiotics at home from a sinus infection I had earlier this year. Could they possibly help alleviate the problem
