It could easily be true that your cardiologist is prudish and not a fan of tattoos, but the medical opinion that he gave you is standard advice. For myself as a person on coumadin, I feel that the possibility of a tattoo has been taken off the table.
My cardiologist said no based on the endocarditis. He said it's the same risk as a dental appt but dental work is essential, while a tattoo isn't. I never got far enough in my research to find out what a tattoo artist would say about tattooing someone on coumadin. Also, I was wondering if my cardiologist may have been exaggerating the risk as he seems a bit prudish and not a fan of tattoos.
I have read that a responsible tattoo artist will not work on someone who is on coumadin.
This is a tricky one. It's not a case of bleeding to death, it's more down to finding a tattooist willing to work on you with your blood so thin. One problem is that if you do bleed too much, then the ink may not stay put.
