Dr Karan Explores · Is Your Back Pain All In Your Head? The Surprising Science of Healing Pain - Dr Anisha Joshi · 6 Jul 2026 podcast

Pain, is that a direct correlate or does that mean that someone has got some tissue damage or a problem, or is it that simple? matched

Yeah. matched

Well, yeah. matched

Perception shapes reality. matched

So if you're told something is a certain way, your experiences will be guided by that information. matched

And I think to go on to say that matched

Pain is also matched

Broadly speaking, the thresholds of pain and the amplification of that and the volume of pain matched

is dictated by your perception. matched

I think the simplest analogy I could think about is if you're getting an injection, say you're getting a vaccine into your arm. matched

If you look at the needle going in, the pain will be worse than if you're distracted talking to someone else and then you're like, Oh, have you done the vaccine already? matched

I think that you know that is matched

you look at it, you're putting in more neurological signals and stimuli and input from your eyes that it's going in, and you're expecting the pain. matched

The anticipation of that pain drives the pain up, right? matched

Turns the volume up. matched

And I guess what you're talking about is someone's getting all these scans and they find all these incidental findings, these incidental omas. matched

They're now gonna think, Oh, I've gotta have that symptom now because it's been proven that I've got the inflammation in my intestine. matched

So you're gonna start feeling those things. matched

The brain's a very weird thing. matched

On the topic of pain. matched
