My dad took weeks(like more than 2 months) to back to being some what confidently ok'ish with things after his coronary artery bypass graft. He needed physiotherapy. His knees were weak and he needed a knee replacement only an year later. But in the after math of bypass surgery I had to hold his hand and make him walk, even feed and took him to rest room personally, I would even bathe him. It took like ages to let him confidently use the toilet on his own. And I'd always keep the toilet door open 'Just in case'. The Knee replacement a year later was obviously more brutal given the bypass was only an year back and we were peak in COVID times. He was infected, and I had sleep on the road as I caught it too(couldn't go home out of fear of infecting the family). Pretty much saw hell in bare form during that(weeks in anxiety, walking in COVID wards and suffering every single minute), and of course that recovery took months, as the drugs they gave him caused a huge spillover of issues. It might just be that as a I child I felt more for my father. But let me tell you major surgeries like bypass grafts, or knee replacements are nightmarish experiences, even more more so in the COVID times today. P.S: This is in Bangalore, India.
