Rusty, I feel your pain. My mother went in the hospital to have a pacemaker put in. They over medicated her on pain killers and she fell getting out of bed. She broke her pelvis and back. The doctor said she was too old for surgery (she just turned 89) and should heal naturally. After a month of just not getting any better, it was discovered that she had an e.Coli infection behind her pacemaker. They had to go in and remove the tissue and infection leaving a hole the size of you fist. After one month in the hospital she is finally recovering slowly at home. She suffered from dementia on and off for the past year. I am telling you all of this to let you know, she came as close to death as she possibly could and survived. I was convinced several times that her feeble body just could not recover, BUT SHE DID. I thank GOD everyday that I have another day with her and that is truly a blessing. She too is 3/4 of the woman she once was, but that is a massive improvement from 1/4 of the woman she once was. Spend as much time as you can with him (call several times a day if you can) as you can, letting him know how much you love him. You have been a good son and you both share many happy memories. Hang in there brother, because we are all praying for your dad. Everyday with them in your life is a blessing and your memories will last a lifetime.
