Not a stupid question, no such thing here. A bladder spasm is a painful contraction of the bladder usually caused by a foley cather. My dr. explained that the bladder walls contract trying to force the catheter out (a foregin object), but it can't of course, because the balloon end of the cath is resting inside the bladder at the bladder neck-urethra junction.
If feels like your bladder is filled to the max, and then wants to explode, except there is no release until the spasm subsides. When I was on a 63 day run of catheter time after surgery, i had them ofen. Some were so bad that I would drop to my knees and it would bring tears to my eyes.
They will prescibe ditropan, a cheap generic drug that really helps. Depending on your doc, you can take it 3 - 4 times a day max. It relaxes the walls of the bladder, since with the cath in place, the bladder is just a holding tank of sorts, and makes it less likely to contract and thus cause the spasms.
On my current cath, I take just one a day, which helps. Since I know that the spasm really won't kill me and no physical harm is being done, I have learned to tough out the lesser ones. Some guys never get them, some like me, get them all the time. The larger the diameter cath, the more likely the chance.
It was funny yesterday. I came home from errands, took off the leg bag, was cleaning the end of the big bag to put back on, and all of a sudden, a large painful spasm came out of no where, never happened to me before without one bag or the other on. Well, pressure will find its way out, and a major burst of urine shot out of the end of the catheter, all over my clothes and the bathroom floor, nothing I could do until it ended. It amazed me how much pressure it came out at, no way of s topping it, so no wonder a spasm hurts so bad when it has no way to relieve itself. Yes, it was a fun mess to clean up.
Hope that answers your question properly. And I hope you don't have any.
