Regarding going to the ER and the OP.
My daughter was undiagnosed for 18 months and we had repeated doctors visits, although she did not have diarrhoea or bleeding as a symptom I do believe that severe pain is reason enough to head to the ER. I have taken both my children to the ER on two separate occasions each because of severe abdominal pain that I was unable to treat at home. The outcomes were as follows:
Sarah 1. A diagnosis of pancreatitis and admitted for 4 days.
Sarah 2. Emergency surgery and diagnosis of Crohn's.
Matt 1. Was already diagnosed with Crohn's. Diagnosed with a ?micro perforation and abscess, admitted for 8 days.
Matt 2. ?Micro perforation and abscess which was later confirmed followed by a fistula. Was in hospital for about 3 & 1/2 weeks.
Pain is not normal nor are any of your other symptoms. It is difficult to say what you may have going on but IBD is something that should be considered. The night sweats may well point to you having an infection. Have you had bloods done for inflammatory markers?
As cupcake as suggested, start a diary of your symptoms and take that with you to every doctor/ER you visit. Have a look at the one we have in our wiki...

Definitely start the process of seeking out other opinions but in the meantime, should you have an episode of severe abdominal pain then head to the ER.
Good luck and welcome aboard!
