Shoulder joint is a unique arrangement defined as ball-and-socket, which moves over a large range. Mobility of such vast proportion makes it susceptible to injuries. The pathologic common reasons for persistent shoulder pain could be bursitis, tendonitis, frozen shoulder, arthritis, or at times dislocation of joint from its socket.
Reasons can be classically classified as under,
>> Tendinitis or bursitis.
>> Overexerting the joint during activities.
>> Weak joint.
>> Acute or chronic dislocation due to muscle weakness or deformed joint.
>> Frozen shoulder.
>> Any bony deformity.
