Forgive the shouting but needs must...
DISCS DO NOT SLIP!
Some of their contents might leak out of their outer casing or the outer casing might stretch and result in the disc explanding, but they do not slip out of place, nor can they be "popped back in".
A better term is a disc herniation or protrusion but not all of these are problematic. Studies have shown that around 30% of adults in their 20s have a disc herniation but they are completely asymptomatic ie it causes them no pain or issues. This percentage increases as we age with a whopping 84% of those in their 80s having an asymptomatic disc herniation. Yes, eighty-four percent!
There also are symptomatic disc herniations of course but with these, the vast majority cause most pain in the leg or arm, rather than the back or neck where the disc is. Infact some people with disc herniations experience ZERO back pain!
So what does this tell us? Amongst other things it tells us that scans don't tell the whole story so it is unwise to rely solely on that as a diagnostic tool. It might be useful in some persistent cases or specific scenarios, but it is not essential in the majority of cases. There are other clincial signs and assessments that are far better indicators of a symptomatic disc herniation, which is one reason why your GP won't send you for an MRI.
Another reason they won't send you for an MRI is that the prognosis for those who do have a symptomatic disc herniation is positive with 60-80% making improvements within 6-12 weeks. By the time you got an MRI appointment through it is likely the disc will have reabsorbed anyway. Knowing this does not make the pain of a genuine disc herniation any easier but because we can use other clinical signs and assessments to diagnose a herniation, we can begin a treatment plan immediately. This brings me to the second part of this myth - discs cannot be popped back in!
The course of healing the disc and any nerve damage that comes with it will happen naturally with time and can happen without any intervention. No need for a physiotherapist, chiropractor, osteopath, sports therapist, or any other therapist that is out there. Yes that's right, your body can heal by itself without any outside help. However, getting some support to reassure you, provide appropriate exercises, manage symptoms, and guide you through the recovery so that your body is an optimal healing environment, can be invaluable.
Sadly though there is no therapist that can "pop your disc back in". They can make a spinal adjustment which is where the joints of the spine are passively moved, and this can result in more range of movement, reduction in pain, and increased function. These are temporary changes though, and other things are needed to make longer term impact. This is the same for any manual therapy intervention whether it is massage, soft tissue release, assisted stretching, mobilisations, KCR etc so I'm not just being critical of spinal manipulation! The true power of any of these interventions is that they can open the door to the person doing what they need to do to help their body heal. It might be that the new range of movement allows them to walk more freely which means their confidence and trust in their body grows again so they can move more often. It might be the reduction in pain means they can get a better night's sleep which in turn allows them to face the next day refreshed and reenergised. It might be that a massage allowed them to let go of some tension they were holding which means they can relax more. It might be having a therapist to listen to their fears and worries about their pain helps them feel heard and supported. These are all valid reasons for getting some manual therapy for a disc herniation (or any physical pain or injury) but it definitely is not to get your disc popped back in!
If you're tired of being told these myths and are ready for an evidence informed and thorough assessment of what you need to get you back on track and independent from repeated treatments, then drop me a DM.
