This is almost identical to what happened to a close relative. The hospital caused the problem and were alerted with plenty of time to intervene, but just upped the pain med, which covered over the damage now happening, until they realized the insistent pain was real and from their prior drug inducing a rip through the colon.
Same basic age, too.
It just sickens me.
Good lord.
People have to monitor their own medical treatments. Always have the temerity to tell the doctors to FO.
