Yes, I had quite a few complications but they weren't in my head. My stent was placed through my groin artery and I had 6 hours of bleeding into my abdomen as well as a terrible headache that caused vomiting. It took weeks to recover from those complications, but I'm several years post procedure and am fine. Fixed my head though! My Dr repeatedly told me it was a quick recovery and I would say that's the general consensus but it was absolutely not true for me. I was noise and light sensitive and had headaches for weeks after. However, it worked.
