As a nurse, Ive seen enough bed sores, sounds like abcess. But from what. At 89, you don't metabolize pain meds as well, fat stores, liver and kidneys all play a role. A simple procedure can be life threatning or just permanently alter your mental status. (Sorry I work 3rd and am tired.) At this point in life we try to stress quality of life. I have seen repaired hips go septic years after repair. Did he receive any injections in the hip that could have caused the bruising due to blood thinners thenn poss for whatever reason an abcess? Either way beekissed is right, what is your goal and what does he want.
