Hope you get better soon Joris, I've been there. In fact mine was a burst appendix resulting in peritonitis, despite me telling the local doctors I was ill, never normally going to the doctors unless my leg falls off, they were adamant it was indigestion......
Fortunately, the doctor on call, ironically a Dutchman, knew his stuff and sent me up the hospital pronto to be operated on that night. Surgeon said I was two days from death......
Hope that makes you feel better!:nut:
