So there i am sat at my desk at work ..it's 8.15 and i've just drank a cup of coffee (something i do every day).No symptoms for the last 5 months. All is well in my world.Then a rumbling starts in my guts. Within 2 minutes i'm sat on the trap with the world dropping out of my ar$e. Sat there a good ten minutes with watery diahroea. Then it stops and i feel fine. Rest of the day is unremarkable. WTF is going on inside me folks!?Every test i've had is normal with the exception of a borderline gallbladder function test. I just don't understand this at all.
