Helping someone realise bladder issues

Hello. I have a relative (62, F) who was diagnosed approx 6 years ago (having been living with MS for approx 15 years they believe). She has suffered from noticeable bladder issues for several years and it’s getting increasingly worse. How on earth do me and my family best broach this? We have tried “subtle” hints many times and tried to discuss use of incontinence pads etc in general life… but nothing has changed. Their odor is incredibly unpleasant and lingers on furniture long after they’ve left. It can’t be a pleasant thing for them to experience either. Any advice hugely appreciated.

Wouldn’t like to be in your position but I guess that whoever gets on well with her is just going to ask her how she is getting on with her bladder - because we have noticed a slight smell. Is there anything we can do to help . Or something like that.

Has she seen a bladder nurse or similar?
