The antibiotic he is on is called SMZ/ TMP. It's a mixture of Bactrim & trimethoprim. It's a sulfa drug. The mass in his throat is an abscess. It contains a cottage cheesey type substance, which indicates that it is an abscess and not a tumor. They think that the bacteria in the abscess is also the bacteria that is causing the canker stuff in his mouth. In his lab resuls, "bacterial sepsis" is marked several times. They did an x ray of his skull (again for free, teaching some students) which showed nothing abnormal. They poked a hole in the abscess but may have to lance it if the antibiotic doesn't work like we're hoping it will. They think the chances of him having Lymphoma or any type of cancer is less than 1 per cent. His weight is still basically the same, he may have gained an ounce. He is still hanging in there, eating and drinking well, even when he can't see well he keeps trying until he finds his food, we help him but he'd just as soon find it himself, lol.
