QUESTION: I have numbness & tingling in the 4th & 5th fingers so I think I may have Carpal Tunnel Syndrome. Can massage help me?
ANSWER: Without examining you it is difficult to say for sure, however there is a good chance that some massage techniques may help you. Firstly, Carpal Tunnel Syndrome (CTS) typically causes numbness & tingling in the 1st -3rd fingers whereas a condition called Thoracic Outlet Syndrome (TOS) affects the 4th & 5th. It is important to note that this is not the ONLY link to such symptoms, but a very common one. Besides TOS, there are also some muscles trigger points that refer to the 4th & 5th fingers. Since this second potential reason for your symptoms is a little simpler, let’s start there.
The “Trigger Point” referral patterns are accurate for about 90% of the population. Within that demographic, 90% of them feel varieties of pain sensation while 10% experience the referrals as numbness, tingling or some kind of “funky” feeling. While the patterns are largely accurate for most people, some may have variations or only feel part of the known pattern. Muscles that are known to refer to the 4th & 5th fingers include Latissimus Doris, Serratus Anterior, Serratus Posterior Superior, Pectoralis Major (sternal), Pectoralis Minor, and Triceps Brachii. While I appreciate the pattern mapping that Trigger Points provide, I no longer do conventional Trigger Point Therapy. I prefer to use myofascial release techniques as I find this method addresses the foundation of the patterns and muscle imbalances better with more complete resolution. If one or more of these muscles are found to be causing your symptoms, this should be a relatively easy fix.
Now let’s discuss Thoracic Outlet Syndrome. TOS is an impingement of the blood vessels and/or nerves emerging from the neck, traveling under the collar bone through the chest, armpit and down into the arm causing numbness in the 4th & 5th fingers. Firstly, the word “impingement” gets a lot of people’s knickers in knots as it sounds traumatic. Impingements can be bones misaligned however a huge amount are caused by old soft tissue repairs which have become fascially adhered to inappropriate structures such as a nerve or blood vessel being entrapped by a muscle repair causing skewed neurological signals and/or poor blood circulation.
There are three common reasons for TOS impingement: Soft tissue scarring along that neurovascular pathway (in the neck or chest muscles); Bony changes from a past fracture of the collar bone which narrow the passageway for the nerves/blood vessels; Or displacement of the collar bone from a poorly recovered shoulder (AC) separation which can create similar pathway issues and myofascial restrictions.
When soft tissue scarring is determined as the cause of TOS using specific orthopaedic testing in office, myofascial release massage techniques can be extremely helpful for successful recovery. This also needs to be paired with some easy homework on the patient’s part concerning strength, stretch and postural awareness for complete resolution.
When the cause is past clavicular fracture or displacement from shoulder separation, the remedy becomes a little more tricky. This treatment plan will still include myofascial release however depending on the age of the injury and severity of symptoms, other medical intervention may be necessary. With fracture, sometimes the remodelling of the bone makes the neuromuscular pathway smaller in places which can put pressure on the blood vessels and nerves which would require surgical intervention.
The fall out from a poorly recovered shoulder separation may very unique to the individual. Sometimes this entails addressing flexibility and strength imbalances in the shoulder which might free up some space. This often includes addressing old scar tissue at the acromioclavicular (AC) joint as well as specific attention to Pectoralis Major (clavicular), Subclavius, Scalenes, Sternocleidomastoid and Trapezius and more generally in Infraspinatus, Supraspinatus, Teres Major/Minor. These last structures are mentioned more to investigate imbalances as they are also attached to the scapula which would have been involved in the original AC shoulder separation injury.
Regardless of the which of these reasons might apply to you, the longer an impingement exists, the more difficult recovery becomes so it’s wise not to procrastinate!
