I Underwent An Aortic Coarctation Stent Repair 5 Days Ago

I underwent an aortic coarctation stent repair 5 days ago and have been doing progressively better. Today I feel pressure in my chest....not painful but steady and somewhat uncomfortable. It is mostly centered in my chest and feels a bit like a weight on my chest. No shortness of breath and does not worsen with deep breaths. I'm more tired today but I also walked a leisurely 3/4 mile last eve (with no immediate adverse effects) I am just wondering if this pressure is a concern or possibly a normal side effect. My stent was placed under general anesthetic, I believe through the groin but I also had a central line in my neck and an arterial lead? in each wrist. (I was told these incisions were arteries but am not sure of their purpose). Thank you for any help you may be able to provide.
