What is  Double Crush Syndrome......

Carpal tunnel syndrome is a double crush syndrome, which starts in the neck and wrists usually, but sometimes is mimicked by the pronator teres muscle, and the symptoms are usually tingling in arms and hands.

 

This condition usually awakens the sufferer in the early hours of the morning with tingling and sometimes an achy pain on the thumb side of the hand, but the little finger is always excluded.

 

Often it is worse in your dominant hand (the hand that you use more often) due to repetitive use of the lower arm causing over activity of the pronator teres muscle and stretching out the brachial plexus of nerves in the neck. 

 

It's common for example in the mouse arm of peoplewho spend endless hours on computers, as well as carpenters who are hammering or using a screwdriver.

​

So too those who are carrying heavy bags in the hands, like grocery shopping, you are straining the median nerve.

 

Any condition that causes swelling in the arm can also affect the nerve. For example, preeclampsia of pregnancy., but perhaps the tingling has already started in the other hand as well.  The pain may spread from the fingers up into the person's forearm.

 

When and how does it affect me......

Do you experience tingling in arms and hands? Usually it's one side only, or one is far worse. It certainly could also cause shoulder pain. You probably have carpal tunnel syndrome. It effects the median nerve.

This is known as a double crush syndrome. The median nerve is irritated in two or more places. While diabetes and an under active thyroid need to be considered, the usual cause of is an irritation of the nerves either

​

1. As the the nerves exit from the cervical spine.

2. As the nerves pass between the first rib and the collar bone.

3. And as the median nerve passes through a tunnel in the wrist.

4. Or as the median nerve in the forearm passes between the bellies of the pronator teres muscle.

Conditions such as pregnancy and wrist injuries that cause temporary fluid retention can also cause median nerve irritation.

The median nerve passes between the two heads of the pronator teres muscle in the forearm where an entrapment may also occur.

​

Experiencing Tingling In The Arms and Hands ......

Tingling in arms and hands has to be carefully examined and followed up, and the pinkie is involved.

​

Pronator Teres:

The medium nerve can also be trapped as it passes between the bellies of the pronator teres muscle, in which  the same pattern of tingling in arms and hands is produced as in carpal tunnel syndrome.

 

Pronator teres syndrome causes a severe pain radiating down lower arm to fingers 1-4, sometimes mimicking Carpel Tunnel Syndrome.
