I received a blood test 2 months ago and still have pain around the area where the needle was inserted. Sometimes radiates down my arm up to my wrist. There was no bruising after the initial blood test. The only question the technician asked me at the time was if I was on blood thinners as there was a lot of bleeding. I am not on blood thinners and am very healthy. I stopped at the clinic today where I received the blood work and she said could be nerve damage. What can I do to heal this injury?
