Angie, I’m so sorry to hear this. I experienced a problem due to MS referred to as Bladder Retention, whereby I was unable to pass urine and collapsed on the stairs when I tried to crawl out of the bathroom. As a result a call was made and I was taken by ambulance to A&E, where they realised that I had 1.7 litres of urine inside, putting pressure on my abdomen. I woke up on a hospital bed, and the urologist had to put a catheter inside, up the urethra, to drain and keep draining by abdomen into a catheter bag. If you had problems going to the toilet, it can send your body into shock, where “passing out” is your body’s way of shutting down.

This to me would be an emergency room visit. Let us know what your doc ended up saying.
