With the Transit Card, the only difference was that the rapid transit fare deduction would be $2.00. The cash fare on buses would increase to $2.00, with transfers no longer available. The CTA's last fare increase in 2009 was $2.25 on trains, with $2.00 the fare on buses.
Testing For Diarrhea. To test for potential causes of diarrhea, a stool sample must be collected. A small amount of the stool should be collected in a sterile container to prevent contamination. This can be done at your primary care provider's office, urgent care, or at an emergency room if the condition has become severe.
Your doctor can give you medications that can help stop the diarrhea and cramping. Sometimes using bismuth medications like Pepto, can cause black diarrhea. But you should have your stool checked for blood and infection just in case. If your doctor cannot see you now, go back to the ER and demand a stool sample. Also, ask for medications to stop the diarrhea and cramping, so that you can feel better.
