Your story is a lot different from my husband. He had triple bypass.. widowmaker was 99% blocked and two others 90% blocked. 70 yrs old.
I’m a retired nurse.
I told him.. don’t forget to ask for pain med if u need it. They won’t just give it to you.
He had pain med day 1.. they pulled his chest tube out 12 hrs after surgery and made him walk with assistance.
He kept saying he had no pain and wanted to go home. They sent him home on day 4. This guy never had any pain!! I was amazed!
He did have some redness around where they removed a vein in his leg , that actually swelled a bit and was his worse discomfort. No back pain.. nothing. It was unbelievable to me. Just walk when u can , drink plenty of water , rest when u need to!
