Your wake up with a dead arm. Or you have persistent tingling down your arm and into your fingers. You have shoulder and neck pain. Your hand feels hot or cold. You may even have weakness.

Does any of this sound familiar?

You may have a condition called ‘Thoracic outlet syndrome’ or TOS.

Hi this is Dr. Andrew Arnold from Cranbourne Family Chiropractic and Wellness Ctr.

Let’s start by defining what this is.

Firstly, this is more common inFemales and between 20 and 40 years old.

TOS refers to a group of disorders which happens when either the blood or nerve flow or both are interrupted by compression.

This could relate to trauma such as a car accident, a repetitive work injury, a sports injury, a congenital issue such as an extra rib and pregnancy.

This is relatively common condition that we see quite of bit of and in general is not a cause for alarm.

So, let’s now focus on the various types of TOS:

  • Neurogenic (neurological) TOS relating to compression of nerves usually at the neck, chest and armpit region.
  • Vascular TOSreferring to blood vessel compression usually by the collarbone and associated muscles.
  • Nonspecific-type TOS where the exact cause is unknown, but the patient presents with all the symptoms in particular pain.


TOS can vary depending on what’s compressed and where.



  • Muscle wasting effecting the thumb pad muscles in the palm.
  • Numbness or tingling effecting the arm or fingers
  • Shoulder, neck or hand pain.
  • Weakness in particular effecting grip.


  • Blue hands.
  • Arm pain and swelling.
  • Blood clots.
  • Weak or no pulse.
  • Coldness
  • Fatigue worsened with activity.
  • Numbness or tingling in particular effecting the fingers.
  • Weakness effecting arm and neck muscles.
  • A throbbing sensation in relation to the collarbone


We manage TOS every week with great results. Chiropractic treatment is safe and effective.


  • Anatomical g. extra ribs at the neck region.
  • Poor posture g. slouching shoulders and forward head posture leading to compression.This could also relate to stroke or emaciated patients who have lost a lot of weight from serious medical treatments such as chemotherapy.
  • Trauma g. car accident, work injury, sports injury…
  • Repetitive activity causing wear and tear, e.g. computer or factory work.
  • Pressure on your joints g. overweight causing excessive stress on joints and muscles around the neck; school kids using over-sized back packs.
  • Pregnancydue to excessively loose joints.


The goal is addressing the compression. This means mobilising the collarbone, releasing muscles and getting the neck and shoulder to work better. We do this using high tech spinal and joint manipulation devices which are highly accurate, effective and safe.

We also address posture by training our patients with posture aids and exercise.
