This is in response to Mayy post. I also had a heart cath about 2 months ago. A couple days afterwards I started with pain in the groin. Which, as you said, grew worse. I have pain into my leg and thigh, going across to my hip bone. I even developed swollen lymph nodes in that area. The heart doc wrote me right off, and just gave me pain killers to take care of it. Can't take them, I also checked on the computer about the femoral or nerve damage, and I guess that is what it is. I went in for tests, and now came out worse than I was. I always liked to walk and bike ride, and cannot do any of that anymore, and doctors don't seem to care. But I know what you mean by the pain, mine does get very bad. I wish I never had the test and wouldn't recommend it to anyone. They do not tell you that this can happen, they say the test is relatively safe. So I guess we are not alone, it must have happened to others also. I wonder if something can be done to cure it.
