Our psyche is able to deal with a certain amount of stress, when the stress is too heavy to deal with, it creates overload that needs to be released.
Here’s a good example of how the mind reacts when stress becomes focused and is too much, unconsciously, for the person to deal with.

Imagine two tennis players, who are also friends. One is very agile on the tennis court, but thinks that he needs to improve his racket skills. The other has very strong and precise skills with the racket, but he believes that his legs and agility aren’t good enough.

The first player works hard to improve his racket skills. He focuses on all the hits that he misses or is hitting wrongly. However, despite putting in maximum effort, he is still not satisfied with the results. He unconsciously devaluates himself and his focus on his perceived lack of racket skills puts stress on his arm or elbow. At this point, the first friend starts to experience tennis elbow pain. And of course, the more pain he has, the harder he finds it to play and he feels even more self-devaluation.

The tennis elbow pain is a smart move on the part of his subconscious brain to reduce his psychological stress. He will likely get tennis elbow because all of his psychological stress is focused so intently on his elbow, trying again and again for the results he craves.

Eventually he has to quit playing tennis and his brain has succeeded in stopping the psychological stress. However, serious self-devaluation has also set in because of his physical problems, which has resulted in ending his tennis playing. All of this, so far, is unconscious. Unfortunately, his tennis elbow has him feeling even more self-devalued because he is unable to play tennis now – even though he wants to. And this, naturally, causes repeated relapses and prevents healing.

To help himself, he needs to see, understand and acknowledge these psychological observations. Once he brings this awareness to his conscious mind, his body can start repairing. The body-mind is brilliant and only needs to be told - or to truly shown - the situation once before it will start repairing and healing itself. The repair process might cause the body a bit more temporary pain ... But just for a few days, until the job is done.

Tennis elbow exercises might cause more damage for now. The best tennis elbow treatment would be to rest the elbow, rather than adding stress. Allow the body to heal - it won't be long before you can start to exercise again.

On appearance, we might think that the cause of the tennis elbow is the repetitive motion of the elbow. But in fact, on closer observation you can see that there is physical pain exactly where he has focused his psychological self-devaluation. The pain is very real and physical but the cause is psychological.
Tennis elbow will materialize in the arm that holds the racket for the man who perceives he is weak with his racket skills. Knee pain will manifest for the other tennis player, who perceives that the cause of his perceived lack of success are his slow legs.

It's also important to remember that elbow (and knee) pain results from subtly different psychological roots in every circumstance. For example, elbow pain - tennis elbow - could result from self-devaluation at work (hating your job).
This is where a consultation with a professional counselor is valuable: to be able to link your particular pain or disease with the 'right' psychological cause. If you try and show the brain the 'wrong' link, healing will not occur. The brain and body-mind is far too smart to be tricked like that!

Author's Bio: 

I have been privileged to have studied with Dr. Claude Sabbah for over ten years. Through his revolutionary teachings, I have been able to develop the HealingRevealed method, which has already helped thousands of people to heal themselves and has the potential of helping anyone, anywhere.

Over the years of practicing and researching, I have explored and tried many alternative approaches and have come to realize that our traditional approaches to illness do not always work. If something is wrong with our body, we try to fix it by putting something external into our body. This rarely results in a total recovery of our health.

Since I have started to explore this principal, I realised that the very nature of disease is found inside us and our health can only be improved if we use this principal in determining our approach to our own healthcare.
