I had a stress test done yesterday to hopefully find the cause of my exertion-triggered dyspnea. They were supposed to do two ABG draws. The first one was done in my wrist and was relatively painless. The second one (done during the cool-down part of the exercise test) was painful and I could feel she hit a nerve and the tech said she needed to try in the elbow since she couldn t hit the artery. When she inserted the needle in the elbow she definitely hit a nerve and I had a painful shock and tingling sensation down my arm, running to my middle finger. I was told I was still not allowed to talk but was obviously in pain. They were not able to collect the second ABG sample. It felt similar to when I had my carpal tunnel test but MUCH more painful. I now have pain in my wrist even though there is pretty much no bruising but I m assuming that s normal. What I am worried about is the fact that any time I fully extend my arm, I have the painful shock all the way down my arm. I want to know if this (the shock/pain sensation) is normal and how long it might take to go away. How long should the wrist pain take to go away and is there anything I can do to minimize it or make it heal faster? I work at an animal hospital and am wondering if I might need to stabilize my wrist.
