Back Pain Solution
Visit a doctor to rule out serious forms of pain like cancer, tumors, or disease. Constant pain that doesn’t change based on the day or what you do is a sign of a more serious cause of pain. BackFitPro.com has qualified clinicians that can help you diagnose your back pain.
Over 50% of people have a disc bulge with zero pain [Source], yet scans like x-rays and MRIs are the primary tool doctors use to diagnose back pain. Do you see the problem with that?
Imagine you have back pain, so you go to the doctor, and the doctor claims your back pain is caused by an abnormality on a scan that isn’t the actual cause of your pain! Scans lead to overdiagnosis and are not linked to pain [Source]. The problem isn’t getting the scan, but rather what we are told about it and what happens next. In the worst case scenario, doctors will use these scans to recommend surgery, but most spinal surgery shows no better results than placebo surgery [Source].
“The notion that surgery will eliminate back pain does not have statistical support.” (Page 14, Low Back Disorders, Stuart McGill)
Doctors recommend rest, but two days of rest is as effective as 7 days rest for low back pain [Source]. Pain-free movement as soon as possible following injury accelerates healing of muscle and bone [Source].
85% of people who visit a doctor for back pain are diagnosed with nonspecific back pain, which means the doctor doesn’t know the cause of your pain. They’ll label you with a fancy name like degenerative disc disease, joint dysfunction, myofascial pain syndrome, or arthritis, but this is just the doctor saying they don’t know what’s wrong with you. These are the people I help.
If you’re currently in pain, get a diagnosis from a doctor. Follow their recommendation, and if you still have pain, book a consultation to work with me directly to identify the cause of your pain and upgrade your quality of life!

About Tom Pfeiffer
I have a long history of back pain, but I've also dealt with chronic pain in my knees, ankles, and shoulders. My passion for helping others comes from my experience of being in pain, visiting doctors, and being unable to find a functional solution.
It has taken years of study, practice, and repeated failure to get myself out of pain, and I'm now completely pain-free and every year I get stronger.
Now after helping hundreds of clients, I have developed a system to identify "weak links" and habits causing microtrauma. This system is what I teach my clients.
I love what I do and I'm obsessed with it. Most people watch sports or tv to relax, while I read anatomy books for fun!
I also enjoy practicing Muay Thai and I'm a voracious reader of self-help, finance, and history. I'm grateful for every opportunity I have to help others. Thank you for visiting my website, I look forward to connecting with you!
