I had a blood test done in the hospital prior to lithotripsy. When he drew the blood I felt a pain down my arm almost like when you hit your funny bone but more painful. It lasted the entire time he drew the blood. I told the nurse that it was the first time I ever felt that. It is now 2 days later and I have tingling and minor pain running from my inner elbow to my fingers. The worst being the top of my wrist. It seems to be getting worse with almost a constant pins and needles feeling. I m getting worried...
