Hi Nettie
I was diagnosed with MM at the end of May this year, just stating my final cycle od CTD
I was told to avoid swimming pools like the plague , like you i enjoy swimmimg , also all public transport, boats & planes . Ie all crowded places
We Go early to quite resturants, I chance the Trafford Centre as its very large, avoiding it at school hols
Family / friends all told to keep away with any colds or infections, Family don't live at home, all sides enjoying colds at present
If I go out I wipe my bit of table with an antiseptic wipe, take antiseptic jell with me for hands
Maybe I am being over cautious , but not had a cold or any other problem during 15 weeks of treatment, touch wood !
All the best
Peter
