Things not going well

The doctors have been unable to find anything that is causing Seth's temperatures. He went up to a massive 42 degrees one night last week. Then a couple days later it appeared everything was getting better. His temps dropped on their own, his vomiting stopped and all was looking hopeful for a swift recovery. Less than 48 hours later, his temps were back and they have been increasing since. He is now remaining in the 39's with Panadol on board. The nurses arent allowing him to get any higher than the mid 39's before dosing him with panadol. He is vomiting, he is pale, weak, dizzy and the runs are back. He had a CT scan yesterday to check his chest again and they have found more spots but nothing they believe the meds he is on can't take care of. They have booked him in for a endoscopy and a possible colonoscopy next week. They believe that as they can't find any viruses or bacteria he may be suffering from GVHD. This can get into the digestive system and cause problems. We will know more next week. He is still on antibiotics, he has become very skinny, particularly in the legs and they are making him as comfortable as possible. He was a little delusional with the temps last night which actually continued to rise even with Panadol in his system. He thought I was telling him the weirdest things like "eating an apple is doom in the jungle". Weird but pretty funny all the same!
