How is resting pain to return a responsibility

summary

Resting pain is the mid-term manifestation of the disease. When the disease develops and the lower limb ischemia aggravates, pain also occurs when you can't walk, it is called resting pain. Most of the pain is confined to the toes or the far end of the foot. It is especially severe at night. When lying in position, the pain is aggravated, the lower limb droop can be relieved, and the night rest pain or rest pain can be relieved. Because the cardiac output is the least during sleep and the amount of blood injected into the lower limbs is also reduced, the pain is often aggravated at night. Whether it is arterial or venous lesions, can cause resting pain, that is, limb persistent pain, the former is more severe than the latter, and it shows that the ischemic aggravation of vasculitis is close to the degree of loss of compensation. Let's take a look at the following.

How is resting pain to return a responsibility

First, most of the rest pain is related to the occurrence of local ischemic neuritis. But the local ischemic neuritis occurs in patients with arteriosclerosis obliterans, followed by thromboangiitis obliterans. Another kind of resting pain is caused by the acute hypoxia of the tissue caused by the sudden obstruction of the tissue artery supplying the implant by thrombus.

Second: skin ulcers or necrosis due to lack of water is another cause of the system. Severe pain is persistent. Sometimes it occurs suddenly or intermittently. It occurs again after a period of time and then after a few minutes. The appearance of pain indicates that the sensory fibers of peripheral nerves are severely stimulated by local inflammation and tissue destruction.

Third: in addition to the above-mentioned vascular diseases, there can also be other factors, such as early foot frostbite and traumatic vasomotor diseases. Ischemic neuritis has some typical symptoms of nerve stimulation, such as sharp pain, radiation to the distal limb, abnormal sensation and burning sensation. Different degrees of tingling, numbness and cold sensation of fingers or toes, etc.

matters needing attention

No matter where the lower extremity venous thrombosis is located, as long as there is venous thrombosis, it can cause inflammatory reaction and affect the sensory nerve, resulting in persistent resting pain. Thrombophlebitis of the vena cava is accompanied by elevated body temperature, tenderness along the superficial vein, erythema, etc.
