Patients with left arm and left leg soreness and discomfort are clinically common for the following reasons: a. Patients with right cerebral infarction can cause left limb hemiparesis with local sensory abnormalities, and due to neurological injury, patients will experience soreness and discomfort in the left arm and left leg. At this time, the patient can be given to strengthen the rehabilitation exercise of the left limb to avoid local muscle atrophy and thrombosis, which will aggravate the symptoms of soreness and discomfort. Second, when the left limb is accompanied by deep vein thrombosis, the venous blood return to the left arm and left leg will be blocked, and a large amount of blood will accumulate in the peripheral superficial veins, which will cause local soreness and swelling. Patients need to subcutaneously inject low molecular heparin, orally take blood activation and stasis pills, and intravenously apply vincristine and other drugs to improve circulation, which can promote the absorption of thrombus in the body and reduce the symptoms of soreness and swelling in the left arm and left leg.
