I'm linking an old story summarizing Jim Henson's final illness, which he ignored until he was too sick, and that was before widespread antibiotic resistance. When I was in grad school, an INFECTIOUS DISEASE MD/PhD (!!!!) who had grad students and taught some of my lectures was ignoring symptoms despite colleagues, other MDs, telling him to slow down and offering to examine him. Later, he disappeared for some days only to return after hospitalization including cutting a drain hole about an inch up from between his eyes. He had a sinus infection, like Busch, that was just septicemic but caught AND chewing a hole through his skull towards his brain. They infused antibiotics into his sinus through the opening when it wasn't draining. He lived and the bullet hole type scar was a lasting reminder of his error and warning to us. If you get a sinus infection that gets worse, see your doc or an ENT!
