Part of the reason is - people are not machines, its extremely hard to diagnose quite a few situations since every body is a bit unique. Add tons of medications and issues every older person has, within their own unique bodies. Add symptoms like chest or abdominal or head pain which can mean hundreds of conditions, some benign some deadly. Add time pressure to diagnose quickly since that's how medical systems are set up. Wife is a doctor so I can see the perspective from the other side too.
I've had a thrombosis formed in my calf after having a broken leg and using cast. I also caught covid during that time, and from what I've read now I believe it increases temporarily clotting of blood for certain people. When cast was removed, leg was still stiff as wooden plank and ankle didn't bend. I wasn't told to keep the leg higher so I didn't. Some weird mild pain started in the middle of the calf after few days, wife suggested it may be thrombosis rather than stiff muscles or tendons. Went to Switzerland's biggest hospital's ER, got blood tests, they were below limit for thrombosis, so I was just sent home.
Pain didn't go away, luckily my wife considered it suspicious and asked another doctor who is an expert on this to recheck. Voila, thrombosis there.
The cause of miss - ER doctors should have done more than just a blood test (even by their own ER protocols, checked that with wife and her colleagues), echography would have shown blood clot in the veins. If it got dislodged and ended up in lungs, that's a quick death within cca 20 mins, ambulance & CPR usually are not sufficient to keep person alive without major brain damage. Or blood clot goes into brain, cutting off some part of it with similar result. One peer from back home died exactly like that (lung variant, the most deadly one).
I am happy you were able to solve it. One of my friends had exactly this problem, but he just died the next day :(
Sorry to have the need to have shared this, but at least it's been on my mind every time I hear someone take their cast off and experience something similar.
