Patients with arm pain after blood draw, according to the specific causes of arm pain, different clinical relief methods can often be adopted: a. If the patient’s needle eye at the blood draw is pressed for a short period of time, resulting in local pain symptoms caused by the oozing of blood from superficial tissues. At this time, it is recommended that patients use local ice to promote capillary constriction, and after 3-5 minutes of continuous pressure, they can switch to external application of hot amyl pack and blood circulation and stasis cream to promote faster absorption of superficial blood stasis, which can reduce local pain symptoms. Second, if the patient inadvertently ties the artery when drawing blood causing bleeding in the artery, it will cause a significant increase in pressure between the muscles, and the patient may experience swelling, elevated skin temperature and increased tension in the arm, causing severe pain. At this time, patients can consider surgery to cut subcutaneous tissue, remove intermuscular hematoma to reduce the local pressure, which can avoid serious complications such as femoral fascial syndrome and relieve the pain symptoms of the arm more quickly.
