Bladder or bowel issues are happening

Questions about urgency, leaking, retention, and constipation

Is what I'm experiencing (urgency, frequency, leaking, hesitancy, not feeling empty) coming from MS?
Could my DMT or another medication be making bladder or bowel symptoms worse?
Should I have a post-void residual or urodynamic test — could I be retaining urine without knowing, and is that risky?
I keep getting UTIs — what's causing them, and can we prevent them?
What medications help overactive bladder — and which are okay for MS cognitive issues (some can worsen brain fog)?
What about bladder Botox or self-catheterization — what are the trade-offs?
For bowel issues — constipation, urgency, or accidents — what actually works? Fiber, magnesium, prescription laxatives, pelvic floor PT?
Is pelvic floor PT covered, and can you refer me?
Should I see a urologist who works with MS patients?
Are bladder or bowel issues a sign my MS is progressing?
