Back-Localized Restless Legs Syndrome–Like Symptoms Without Limb Involvement, Accompanied by Urinary Urgency and Generalized Heat Sensation, With Differential Responses to Dopamine Agonist Therapy and Somatosensory Stimulation: A Case Report
This case report describes a 50-year-old man with an atypical presentation of Restless Legs Syndrome characterized by back-localized discomfort, urinary urgency, and generalized heat sensation, which showed complete relief with the dopamine agonist ropinirole but only partial improvement with acupressure mat therapy, suggesting distinct yet interacting neural mechanisms for somatosensory and autonomic symptoms within the RLS spectrum.

Imagine your body has a tiny, grumpy alarm system that usually goes off in your legs at night, making you feel like you have to wiggle them just to feel okay. That's a common condition called Restless Legs Syndrome (RLS). But in this strange and fascinating case report, a 50-year-old man had a version of this alarm that decided to skip the legs entirely and set up shop right in the middle of his back, between his shoulder blades.
The Midnight Trio
Every night, about 30 to 60 minutes after this man fell asleep, a "trio" of trouble would wake him up. First, his back would feel restless and uncomfortable, like it needed to stretch or move. Second, he'd suddenly feel a desperate need to run to the bathroom, even though he didn't have much to pee (sometimes needing to go every 10 minutes!). Third, he'd feel a weird, general heat sensation all over his body, like he was suddenly wearing a heavy winter coat in the middle of summer.
These three symptoms always showed up together, like a synchronized dance routine, and they only happened at night. If he rolled over or stretched, the back feeling would calm down for a bit, but it would usually come back within an hour or two.
The "Magic" Pill vs. The Spiky Mat
The doctors tried two different ways to stop this nightly drama, and the results were like a magic trick with a twist.
First, they tried a medication called ropinirole (a dopamine agonist). Think of this pill as a master switch that turned off the entire alarm system. When the man took 0.25 mg of it an hour before bed, the back restlessness, the bathroom urgency, and the heat sensation all vanished completely. It was as if the trio had never existed.
Then, the man decided he wanted to try something without pills. He started using an acupressure mat (a mat covered in tiny plastic spikes) on his back for 20 minutes before bed. This is like giving your back a very intense, prickly massage.
Here is where the story gets interesting: The mat was a superhero for the back! It made the restless back feeling almost disappear, just as well as the pill did. But, the mat was only a "sidekick" for the other two symptoms. It helped the bathroom urgency a little (maybe 60–70% better) and the heat sensation a tiny bit (20–40% better), but they didn't go away completely like they did with the pill.
What's Actually Going On?
The authors of this report suggest that this man's condition is a rare, back-only version of Restless Legs Syndrome, which they call "Restless Back Syndrome." They think the reason the pill worked on everything while the mat only worked on the back is that the body might be using two different control systems.
Imagine the brain has a "dopamine network" that acts like a central command center. This center seems to control both the weird back feelings and the bladder/heat issues. The pill talks directly to this command center, turning everything off.
The acupressure mat, however, seems to work on a different level—like a local security guard at the spinal cord. It sends strong "prickly" signals that distract the brain from the bad back feelings (a concept called "gate control"). But this local guard doesn't have the authority to shut down the central command center's control over the bladder or the body's heat, which is why those symptoms lingered.
What the Paper Says It's NOT
The report is careful to say this isn't a simple case of a bad back from a slipped disc or a urinary tract infection. The man had no pain in his legs, no fever, and his urine tests were clean. It also wasn't caused by his other health issues like his past depression or his glaucoma eye drops. The symptoms were unique to this specific nighttime cluster.
How Sure Are They?
The authors are suggesting this is a new way to look at RLS, but they aren't claiming to have solved the whole mystery. They admit they didn't do a full sleep study (like a camera recording brain waves) or a deep urological exam to rule out every single other possibility. They also note that the man's own memory of how bad things were before treatment might not be 100% perfect.
So, while this case suggests that back-only RLS exists and that acupressure mats might be a great drug-free option for the back part of the problem, it remains a single story. It's a fascinating clue that helps doctors understand that sometimes, the "restless" feeling can move to the back, and that different treatments might need to target different parts of the body's complex wiring.
