I did not need to wait 6 months for an appointment to get this information. Let's hope it helps you.
BTW, regarding the spelling of diarrhea, as a retired English teacher I think we should stop using words that are too hard to spell. How about saying "the runs" instead? Also, there's a good old-fashioned Anglo-Saxon term but somehow it eludes me. Be well. PB
Irregardless, I think you have a medically urgent condition and if your doctor won't help you with it you should seek treatment at the ER or the equivalent of urgent care in Canada.
Sometimes even here in the US things happen quicker if you go through the ER!
