The Causes of Pain in Arm Days after Blood Test
Getting blood drawn may be painful but only for a few minutes in most cases. Once the needle is removed from the vein – it’s sweet relief. On the other hand, in a small number of cases the pain of venipuncture can persist even after the needle is removed, and you’ve returned home. What causes pain in the arm days after a blood test? It Could Be a Hematoma
One cause of pain is a hematoma. A hematoma is a collection of blood that forms outside the vein. During a blood draw when the needle pierces the vein, it can become temporarily damaged causing blood to leak out into the tissue. The leaked blood forms a pocket of blood, which can be painful. It’s not uncommon for the area around a hematoma to turn red or blue, and the surrounding tissue to become swollen.
