2 days post op

Hi I am 2 days post op and today been having some pressure like senasation in my mid chest, not like pain or a full short of breath feeling, just like a sense of it. Normal vitals. Normal breathing, no pain. My problem is I have sever health anxiety about blood clots like PEs. I don't know if ita like a sensation from the gas used or if I'm just freaking myself out. I have no history of clots or clotting conditions either and I'm young at only 30 years old.
