Content: This can cause not only pain, but numbness and tingling in the arm or hand. If the phlebotomist hits a large nerve, a person may feel a brief, shock-like pain as the needle nicks the nerve. Fortunately, most venipuncture nerve injuries heal, but it may take weeks or months for the arm discomfort and nerve symptoms to completely go away. In rare cases, the nerve damage can be permanent. Sometimes, swelling that comes from a hematoma causes pain, numbness, and tingling by putting pressure on a nerve. This usually subsides once the hematoma has resolved. Not All Arm Pain after a Blood Test is Serious
It’s normal to experience a little discomfort and soreness for a day after a blood test, but arm pain that lasts longer is less common. When it occurs, the best course of action is to see a doctor and make sure there’s no sign of nerve damage, hematoma, or infection at the site of the needle stick. Most needle sticks hurt, but, fortunately, they don’t cause lasting damage. References
