Feeling sick for 3 1/2 weeks now. Nautious, dry heaves, feverish, head feels hot and clammy, change in bowel movements, weak, dizzy, tired, heavy feeling arms and spaghetti legs, stomach bloating , indigestion/burping, no appetite . Had abdominal ultrasound - came back normal, regular blood test normal. Could it be H-Pylori or some sort of intestinal bacteria since I ve been feeling really bad for 3 1/2 weeks now? Antibiotics?
