Pain is something that we all will experience at some point in our lives. It is inevitable. But the question is, how will you deal with it? With this question in mind, we want to provide you all with accurate information about what pain is and what pain is not so that you can make an informed decision about your own health!

Pain is normal.

Pain is actually a normal experience and you may not know it, but you should be thankful you can experience it. Let’s say you are walking barefoot and step on a piece of glass you better hope you can experience pain! If not, it won’t be good news. You see, when your pain system is acting appropriately, it acts similar to an alarm system.

Alarm systems function to protect you and will go off whenever there is a threat. This is a good thing. Our brain produces pain similarly whenever it feels threatened. This allows us to dig deeper and figure out why something may be bothering you. However, there are times when an alarm system can be hypersensitive and go off with no real threat around. This is often the case when people experience persistent pain.

In order to better understand pain being a perception of threat, let me explain further by a common example. Let’s say that you are walking across the street when you twist your ankle. You fall to the ground, and look up to see a truck driving directly towards you. Do you think you would experience pain in that moment? Probably not. You would probably get up and move out of the way to safety on the other side of the street. Now, let’s say you are walking in your house and twist your ankle in the same fashion? Do you think you would experience pain in this situation? Probably so, because it is the biggest threat at the point-in-time. I hope this helps demonstrate that pain is specific to a wide range of inputs and your brain’s interpretation of safety.

Pain does NOT equal damage.

Time and time again, study after study, we are finding that changes on x-rays, MRIs, and other images have a very poor correlation with pain. Here are a couple of studies supporting these findings.

• Ultrasound of 411 individuals without pain, 23% of people had a rotator cuff tear. (1)
• CT scan or MRI of 3110 individuals without pain, 30% of 20 year-olds and 84% of 80 year-olds had a disc bulge. (2)
• MRI of 5,397 knees in people without pain, 19-43% had arthritis (age greater than 40 years-old) (3)
• Sham surgeries (performing a procedure with no structural change) were found to be just as effective as surgeries in decreasing pain. (4)

We, as healthcare providers, have historically done a terrible job of providing our patients with this GREAT news. We have instead caused unnecessary fear and hyper-awareness of imaging findings that assume that you are damaged. In actuality, these findings may or may not have anything to do with your current pain experience. It is very important to know that as we age, our bodies change and it’s totally okay and normal! My favorite analogy to understand this concept is that changes on images are like wrinkles on the inside. Just as we know that we develop wrinkles as we age and that they do not correlate with pain, we know that there will be changes on your x-rays and MRIs that are no more than wrinkles on the inside. There are obviously exceptions to this (i.e. when there is a true structural issue causing your knee to give way such as an ACL tear from a one-time incident, etc) but overall, the findings have no direct correlation to your pain experience. Since we now know these normal imaging findings, you can move away from fear of your imaging and truly begin the road to recovery.

Rest is usually the enemy.

In the past, due to fear of further damage, you may have thought or been told to just take it easy or perhaps rest altogether. Although there are times when relative rest is beneficial (training/modifying around the problem area), total rest is almost never the case. This is not just a recommendation or simply our opinion, this is time and time again supported in the research. Sadly, our healthcare system as a whole has done a very poor job of promoting the continuation of exercise and physical activity. In our upcoming blogs we will discuss ways to continue moving while experiencing pain. We hope that you all will join us in spreading the news that it’s best to keep it moving!

Moving Forward

As we journey together through our upcoming blogs, we hope that you will feel better equipped to make informed decisions about what is best for your health and fight back against the societal norms. Do your research. Ask further questions. And keep it moving. We are here to help and want to see you live a healthy, fruitful life!
