My mother in law was recently taken to the ER with severe back pain. A CT scan revealed what is believed to be some type of cancer in several vertebrae, plus one is fractured. Doctors say she needs a PET scan which must be done as an outpatient. She is unable to walk and is pretty much confined to a bed now, so she opted to go to rehab in hopes of getting better so that she could get the PET scan. That doesn’t appear to be working. Day 4 of rehab, she slept most all day and on day 5 (today) she doesn’t make sense when she talks, isn’t sure what time of day it is, or even what day it is. She is confused and will repeat everything you say.
She has COPD and is supposed to be on a bipap machine each night, but she hasn’t used it in at least a month.
Is the build-up of CO2 causing her erratic behavior or has the cancer spread to her brain?
Should we insist that her regular physician come see her in rehab?
