Shoulder periarthritis night ache reason?

summary

For many patients with scapulohumeral periarthritis, every night, the affected area will appear great pain. Why does this happen? If you want to avoid this situation, we should first know what is the main cause of night pain in patients with scapulohumeral periarthritis. Now let's talk about it.

Shoulder periarthritis night ache reason?

Periarthritis of the shoulder is characterized by multiple pain in the shoulder and arm, and is characterized by aggravation of pain at night. According to the basic research and clinical observation, on the one hand, the pain of shoulder periarthritis is caused by congestion and edema of aseptic inflammation, compression and stretch of peripheral nerves (tendons and ligaments are dense tissues, and slight swelling can also cause stretch reaction).

On the other hand, the stimulation of inflammation, hyperemia, blood stasis and so on make local inflammatory products accumulate and stay (such as histamine, 5-hydroxytryptamine, kinin, potassium ion, hydrogen ion and so on). These substances themselves have a strong effect of stimulating pain nerves and causing pain. In addition, these inflammatory products can directly act on the smooth muscle of small blood vessels, cause the expansion and congestion of small blood vessels, aggravate the swelling and stasis, stimulate the vascular wall, increase the permeability of vascular wall, increase the exudation of plasma and leukocytes, and make the inflammation generalized.

When resting at night, the skeletal muscle is in a resting state, in which the small vascular smooth muscle tension is higher, the blood flow resistance is larger, and the blood flow is less than that in the daytime (the blood nutrition in the body is concentrated to supply the heart, brain, liver, kidney and other important organs to ensure their functional activities). When the amount of blood supply to the inflammatory area of the shoulder joint is less, the metabolites of inflammation can not be quickly transported away, diluted and decomposed. The higher the concentration is, the stronger the stimulation to the pain nerve is. At the same time, the higher the concentration of these metabolites, the heavier the local swelling and stasis, and the stronger the tension and compression, so at night, the pain in the lesion area will increase.

matters needing attention

For patients with scapulohumeral periarthritis, the causes of pain at night are the above points introduced by experts. If patients want to avoid this situation, they can start from daily nursing. There is also periarthritis of shoulder patients can also be appropriate for some exercise, can help reduce the pain.
