I had this done last week and am still feeling awful. The artery spasm ed throughout the procedure and was very painful. The bleeding took 2.5 hrs to stop. I then had a migraine for 2/5 days after [female]. The procedure was done last friday and today is wednesday and i can't use my right hand/arm fully. I am still taking Motrin daily for the pain. Was not a pleasant experience for me. However, I don't have any blockages :)
