Angio Seal

On August 5th or on so; early part of August, 2011 I was admitted to Sunrise Hospital for an angioman for right carotid antery. I could not have another emdnterecomy on carotids due to the fact that i've already had 3 carotid endaterectomies.
So they went in through groin & found the right corotid was blocked 97%. So the doctor elected to go back into the artery again & to place a stent in the artery & then sealed the would with an angio seal.
When I was released to come home, I had such an excruciating pains in my legs & head & then sores appeared on my right leg; horrible looking things -- they would open, spew out blood & close again. I went to a dermatologist; he never saw anything like this before -- gave me antibiotics but to no avail.
I went back to the Cardio Vascular surgeon on November 2011 and had him remove the Angio Seal. Some of the sores went away, 2 did not. The Angio Seal was very infected and a biopsy was done on one of the sores in my leg.I am miserable -- the pain in my leg and head is the most excrutiating I have ever had in my life.Now ,I have an appointment with a Neurological scientist clinic in June. I need help desperately I've been sick almost a year I do not know who to contact to help me.
Any ideas, please! I need help. I also have congestive heart failure and Cardio Vascular problems.
