B cell lymohoma is a treatable cancer (old-people cancer) I really wonder why it seems like they aren't trying to get rid of that first? From what Jim said (and from my memory) it sounds like he had a lymphoma tumor on the back of his head which was either biopsied/removed. He then gets a bunch of neurological symptoms following that. You had a tumor close to your brain then had neurological symptoms, could they be related? Biopsy of a tumor can lead to the tumor becoming more aggressive, so it's not like you can sit on that all day.
Get rid of the cancer, instead of testing for "unicorn aids," or to see if he has "leprechanitus"? I joke a little, but in all seriousness B cell lymphoma is a more aggresive cancer, and that, in part, is why it responds so well to chemo. It seems like Jim has a diagnosed housefire, the drapes are burning in the dining room, but the doctors are wondering if he has a leaky pipe in the basement. Again, to me, it doesn't make sense. Which could be just due to lack of detail from the patient, but there is an aspect where you do have to advocate for yourself at some point.
Hopefully this hiatus is them treating the cancer, and not just leaving it on the back burner to metastasize to who knows where, while they look to see if he has terminal sudoku in his left shin. Scans have a limited resolution, so they won't see everything, but you had tumors close to your brain, followed by neurological complications. To me, an online idiot, this seems very much related.
Anyways, sorry for the rant, dealing with doctors can be frustrating at times (I'm geting second-hand frustration just hearing about you troubles). I know what that's like. Get better you potato nigger. You can't enjoy large-breasted asian women if you're dead.
