Yes, I would. Especially if you can use a bathtub, not a small container of water to "soak". It's the actual swimming motions that can really help- but you don't want her in deep water, just about 3" of luke-warm water. Remember you're 98.6* so if the water feels warm to you, it's probably over 100* & too hot for your snake! Use a thermometer for best results- water should feel cool to you, but not cold. And never leave a snake alone in the tub...not that you would.
You want her to stretch out & make "S" motions- support under her mid-body so she doesn't actually go anywhere.Spend at least 15-20 minutes doing this- she needs the hydration too.
I've dealt with a snake that had urate stones (aka "cloacaliths") before, that's how I know about them- they're not common. Snakes can also ingest things while swallowing prey that they cannot digest & that can cause a blockage, or they can develop a fast-growing tumor- so if she doesn't defecate for you, it's best to have a vet sort this out. Might need an x-ray too. But keeping my fingers crossed that the "swimming" does the job. Don't worry about the "stress" of this swimming in the tub- vets are stressful too- always better if you can resolve things at home.
BTW, go real easy on the "massage"- you can cause harm, depending on what the blockage is.
