When periarthritis of the shoulder flares up, the stiffness and soreness that spreads from the scapula to the entire arm always make one feel restless. At this moment, a PVC hot water bottle filled with hot water became my most considerate "therapist".

After working at a desk for two hours, my shoulders and neck felt as tight as if they were bound by an invisible rope. I will adjust the water temperature to around 50℃, wrap the hot water bag with a thin towel and press it against the most sore part of my right shoulder. The flexibility of PVC material is just right, allowing it to fit and wrap along the curvature of the shoulder peak. The heat seeps slowly into the muscles through the fabric, like countless warm hands gently pressing. Ten minutes later, the originally tense trapezius muscle gradually relaxed, and the strange "click" sound when raising the hand also became much lighter.

Before going to bed at night is its "golden working period". I will stuff a hot water bag into the shoulder sleeve of my pajamas to keep the warmth seeping into my shoulder joints. The PVC material has excellent airtightness and can maintain a suitable temperature throughout the night. It neither burns the skin due to overheating nor causes rapid hypothermia. Wrapped in warmth, even the pulling pain when turning over has been alleviated by more than half. The range of motion of the shoulders in the morning has significantly improved, and it is no longer difficult to reach the top layer of the wardrobe with one's hand.

During the breaks from doing housework on weekends, I also use it to do simple hot compress exercises: holding a hot water bag, I slowly rotate my shoulders in circles, allowing the heat to penetrate deeper into the fascia as I move. The surface of the PVC hot water bottle is smooth and does not hurt the hand. Its weight is also just right. It can provide continuous heat without adding extra burden to the joints.

This seemingly ordinary PVC hot water bottle, without complex functions, uses the most simple warmth to gradually relieve the discomfort caused by periarthritis of the shoulder. During those days plagued by pain, it was not only a therapeutic tool to relieve soreness but also a silent and warm comfort.
