hello missb and welcome to NT,
you've found a great place to land. i'm sorry you're going thru all this worry.

i don't know how the medical system works in bc but based on living in the usa i have a few suggestions. try to get a copy of your mri cd and report so that if you see other drs you can just bring your records.

it's best to have an mri with and without contrast so that if you have any active MS lesions they can be easier to see by the radiologist.

it doesn't sound to me like your dr(s) are really listening to you. do you have a pcp (primary care dr)? sometimes they can take the reins in a pt's care and coordinate with other md's. can you take a friend or family member who can help you advocate for yourself in front of the dr?

try to be respectful but firm and tell them something is wrong and you need to find out what it is. urinating once a day isn't good. your bladder can get stretched and then it can be hard to go. also the urine can back up and you can be suseptible to bladder infections.

it sounds like maybe a urologist could possibly help you with that. even if you don't have MS there are ways/meds of dealing with some of your sx's (symptoms).

please let us know how you are.
