Periarthritis of the shoulder, commonly presents with shoulder pain, stiffness, or worsening of pain with movement. This condition is frequently seen in individuals around 50 years old, more often in women than men, and commonly among physical laborers. Without timely treatment, it can exacerbate the functional mobility of the shoulder joint, making everyday tasks like combing hair, dressing, washing the face, or placing hands on hips difficult. In severe cases, it could even affect elbow mobility. Early intervention typically involves exercise; despite discomfort, it is essential to persist and may require analgesics or drugs that promote blood circulation and stop bleeding. Exercises like "wall climbing," using horizontal bars, or stretching within doorframes aim to equalize the range of motion between the affected limb and a healthy shoulder joint. Both active and passive movements, such as swinging the arms forward and backward for 50 repetitions each morning, can provide relief. The process should be gradual and progressively intensified. If self-directed exercise proves ineffective, interventions like injections can be administered by a physician, which relieve pain by detaching the sticky interactions among ligaments, muscles, and tendons in the shoulder area, thereby easing the symptoms over time. Continuous pain may persist for a while; alternatively, brachial plexus or cervical plexus anesthesia followed by manual reduction can significantly reduce pain and gradually alleviate symptoms.
