<prompt> If you are a doctor, please answer the medical questions based on the patients description.Isn t it true that sharp pain in one s right shoulder could indicate parasites in the small andor large intestines i.e. amoebic dysentery which could be seen by the host amoebic cysts and trophozoites...all stages of development in one s stool, cause bloating, gas, stomach distention, terrible abdominal pain, diarrhea, constipation and progressively get worse if not treated with the appropriate antibiotics and eventually cause the death of the host? Fact or Fiction: Amoebic dysentery has been eradicated in North America. Amoeba and trophozoites cannot be seen by the naked eye. Amoeba generally float on top of the toilet water, easily visible. Standard OP lab tests cannot detect amoebas and trophozoites. The infected stool must be submitted to a lab that has the special equipment and appropriately trained personnel in order to detect amoebic dysentery disease. Two or more antibiotics will be necessary to eliminate such parasites; long term if the host has been infected over a long period of time. Thank you, Edward DeBusman  <response>: Hi, There is no direct relationship between intestinal infection and shoulder pain. Reasons for both are entirely different. The intestinal infection will lead to diarrhea, bloating and indigestion but not shoulder pain. Reason for shoulder pain may be muscular pain or joint abnormalities. A detailed clinical examination is needed to assess the cause of shoulder pain. Hope I have answered your query. Let me know if I can assist you further.
