I am a 44-year-old female who recently spent three days in the hospital following runs of v-tach. I underwent a cardiac cath, which showed no heart damage, so I was put on lopressor, which seems to control the v-tach. It's been five weeks since the catheterization, and I'm still sore in my leg. The toes of my right foot about two weeks after cath suddenly became swollen and sore and itch terribly. My cardiologist said it is abnormal to be sore one week after catheterization, and he asked me to come to the office for a checkup. They didn't run any x-rays, but pressed around my leg and listened with a stethoscope and said they weren't concerned and gave me a couple more weeks before doing an ultrasound. The doctor said the foot pain doesn't seem to be related to the catheterization, but I find that hard to believe that there's no connection. I'm beginning to think that maybe I'm allergic to the collagen plugs they put in me. Is that possible? And if so, do those plugs eventually dissolve? Thanks.
