The shoulder is the summation of several joints that give us strength and range of motion to the arm. In other words, it is a combination of the collarbone, upper-arm bone, and shoulder blade. On the other hand, shoulder pain or impingement is a problem with the rotator cuff. The most possible causes of this pain are:

Loss of cartilage
Irregular posture
Heart attack
Tension in the muscles between the neck & shoulder
Dislocation of the shoulder
Spinal cord coup
Burning in the ‘bursa’
Frozen of tissues
Damage to the muscle and tendons
Bone spurs
Arthritis

Who doesn’t know that having a sound body is the precondition of having a sound mind! Sometimes we do shroud or ignore our shoulder pain and repent afterward. Harboring pain is simply absurd. It’s all about forfeiting in near future. Hopefully, you don’t want to go astray.
