Sudden bulging and bruising pain in the blood vessels of the fingers is commonly caused by trauma and low platelets.
1. Trauma: due to life after inadvertent extrusion or collision, capillary rupture will be out of blood stasis phenomenon, thus causing blood vessel bruising. This situation generally does not require special treatment. If there is obvious pain accompanied by swelling, you can apply cold compresses to the injured area for 20-30 minutes, 3-4 times a day, and then change to hot compresses after 48 hours, and it can be fully restored to normal after 2 to 3 weeks.
2. Low platelet: Due to the impaired coagulation function of low platelet, when the blood vessel wall is damaged, the blood leaks out from the blood vessel to the outside of the blood vessel, thus forming a bruise after subcutaneous bleeding, i.e., the blood vessel is suddenly bulging and blue, which can be accompanied by pain. At the same time, when platelets are low, the damaged blood vessels can not be repaired in time, which can also cause finger blood vessels suddenly bulging and bruising pain.
Clinically, there are many factors that can cause sudden bulging and bruising of blood vessels in the fingers, such as hemophilia, aplastic anemia and so on. Patients should consult a doctor in time, under the guidance of a professional doctor, to clarify the cause of the disease, and choose a targeted way to alleviate the treatment.
