I don’t know if this exactly fits the topic as it is more a question/comment on treatment of symptoms… but here goes anyways.
Currently a close family member of mine is going through chemotherapy for stage 3 bladder cancer, their most chronic symptom from treatment has been a massive increase in saliva production. While this isn’t a painful symptom, so to speak, it has dramatically effected their ability/willingness to leave the house (they carry a plastic cup with them as a spittoon wherever they go). I don’t know if I’m asking for ideas or just… venting? But yeah, cancer complicates everything, doesn’t it.
