Debbie - Sorry about the UTI. You should start feeling better in a few days after starting the abx. Also, hygiene is only a part of preventing UTI's. With many of us MSers, completely emptying our bladders is an issue and a cause of UTIs. (I'm a retainer myself but haven't had an infection yet. Knock on wood.) If I remember correctly, you had urodynamic studies done, right? It may be time to go back to the urologist and get checked again and possibly start some sort of treatment. Hang in there and I hope you start feeling better soon.
