Most of us have experienced that strange mix of discomfort and satisfaction — the “no pain, no gain” feeling that comes with exercise, eating something spicy, or pushing just one step further when running. But why does the body sometimes register something painful as pleasurable? Why do some sensations that should feel unpleasant still give us a sense of reward?
These fascinating questions were explored in a recent episode of the BBC World Service podcast CrowdScience, where Dr Robin Chatterjee, Consultant in Musculoskeletal and Sports & Exercise Medicine, discussed why pain can sometimes feel good. The episode, titled “Why does pain sometimes feel good?”, brings together science, lived experience and expert explanation in a way that’s both accessible and thought-provoking.
Understanding “Pleasurable Pain”
In the CrowdScience episode, host Anand Jagatia unpacks a seemingly paradoxical phenomenon: why do people willingly seek uncomfortable experiences? From eating fiery chillies to intense exercise, certain forms of pain don’t just fail to repel us — they attract us.
Dr Chatterjee helps explain this from a musculoskeletal and exercise perspective, including why sensations like the “runner’s high” are not simply about physical stress, but about how the body and brain respond to effort and discomfort. This builds on broader scientific research into pain, reward pathways and affective valence — how the brain interprets sensory experiences as positive, negative or somewhere in between.
For listeners interested in the neuroscience side of this topic, ongoing research explores how brain regions involved in reward and pain perception can overlap, particularly during sustained or repetitive stimuli. External resources on affective neuroscience provide helpful background, such as work from research groups studying brain representations of pleasure and pain.
Why this matters for everyday movement
So what does this mean for people living with aches, stiffness or ongoing discomfort? The connection between pain perception and movement pleasure can help shift how we think about activity — especially in settings like rehabilitation, exercise routines or moving after a period of inactivity.
Understanding that not all pain is equal, and that the body’s response to effort can involve both discomfort and positive reward, helps us:
-
Build more sustainable exercise habits
-
Recognise the difference between productive discomfort and harmful pain
-
Approach musculoskeletal challenges with curiosity rather than fear
This aligns with our overall approach at Panacea Health, where personalised care aims to support confident movement and long-term wellbeing rather than quick fixes or generic advice.

A conversation worth exploring
Dr Chatterjee’s contribution to the CrowdScience episode is a great reminder that pain isn’t simply something to be avoided — it can also tell us something about how our bodies adapt, reward effort, and learn new patterns of movement.
The podcast episode, “Why does pain sometimes feel good?”, is available on the BBC World Service site and wherever you listen to podcasts.
Bringing science into everyday movement
Whether you’re interested in the science behind the body’s response to challenge, or you’re navigating your own journey with activity, listening to thoughtful discussions like this can open new ways of thinking about movement and pain.
At Panacea Health, we believe that understanding the why behind discomfort — why a run can feel good despite muscle burn, or why a stiff joint improves after gradual movement — can be empowering. It helps people move not just more often, but more confidently and thoughtfully.
If you’re curious about how your own movement patterns and pain responses connect, our team of musculoskeletal doctors in London are here to help. Learn more about assessing pain and personalised care.
