I was in the hospital a month ago today and thought I was having a heart attack they did a catheter now a week ago in the same leg I started to get real bad pains in my foot mainly my right big toe and that was the same leg that the catheter was done. Now the pain has stoped but my toe is real cold and the nail is turning blue and going numb should I worry.
Hello, Regarding your concern, I would explain that your symptoms do not seem to be related to the catheterization.  For this reason, I would recommend consulting with your attending physician for a physical exam and performing some tests
