Two weeks ago I was having a ct with contrast. The rad. teck first stuck me in my right hand it blew and bled pretty good had a buise in hand until a few days ago . Pain from site has not continued up my arm and followed a line from wrist to bend in my arm around under top part of my arm to armpit the muscles in this area hurts feels like it is pulling. I had a sonogram done no bloodclot but np said to use heat. I am concerned about this!
