Muscles which are tightened with trigger points can sometimes squeeze on surrounding nerves or blood vessels.
If a nerve is squeezed, it can result in a numbness or pins and needles sensation in the area which is served by that nerve. This is very common in the arms and hands, and is given the label if ‘Repetitive Strain Injury’ or ‘Carpal Tunnel Syndrome’.
If an artery is squeezed, it can result in a distant body area feeling cold, common in hands. If it is a vein, it can impede the return of blood to the heart, resulting in a swollen limb, often found in feet and ankles.
If any of these conditions are a result of tight muscle compression, then a deep tissue massage can go a long way to addressing these problems.
