My mom has had sharp abdominal pain, yellow/green/black diarrhoea and chills for nearly a fortnight. We have been to the local doctor twice now, and they have only prescribed Advil, which has had no effect. Do you have any idea as to what sh could be experiencing?
Unfortunately the details you have provided are not adequate. The exact location of the abdominal pain is important, and it is hard to comment without proper examination. It is possible that she has a gastrointestinal infection which is also the likely cause of diarrhea. It is also possible that she has some problem with gall bladder and the biliary system, but it can be commented only after proper investigation. Had I been the treating physician, I would probably not have prescribed Advil which contains ibuprofen that could worsen the pain if it was due to gastritis. Please talk to your doctor about what he feels. Alternatively, you could also get a second opinion from another doctor.
