Brief Answer: Probably you are facing stomach viral infection... Detailed Answer: Hi, Thank you for sharing your concern with XXXXXXX The pain between your shoulder blades could be related to: - spondyloarthrosis - pancratic/liver problems - chest/lung/heart problems. Your olive green stool indicate for indigestion and that your feces are moving very fast through your bowels most probably due to a recent stomach bug you had. Another reason could be related to something you have eaten (including green leaves-spinach, food coloring, iron supplement you might be taking, any drug like indometacin, etc.) If there was no change or such foods introduced in your diet; then, further tests are needed: - chest X-ray - EKG - cardiac echo - abdominal ultrasound - liver/pancreatic enzymes and tumor markers - examination of stool for ova/parasites - culture of stool for bacteria/candida - fecal occult blood testing Depending on the test results, the most appropriate treatment will be prescribed. Meanwhile, I suggest to: - take tasectan and probiotics to stabilize intestinal flora - take acetaminophen for the pain - apply warm clothing to the pain area - drink more water If no result, further evaluations should be carried out. All the best! Dr.Klerida.
