Yes, they are doctors not gods and may have passed their training courses by the narrowest of margins and perhaps don't keep up with the latest knowledge.
I refer to them as Witch doctors because with many you stand as much chance of successful outcomes as you do with the Voodoo educated variety.
I have seen 2 messed up surgeries with close folks in the last year.
One is dead after a routine surgery and the other lost full use of a thumb due to a crappy tendon repair.
I hope your fathers condition improves and I can relate that you must be furious for the lack of care and attention to detail by your former physician.
Unfortunately with the Obama Medical plan your Physicians will be further overwhelmed by the patient load and you can expect even less care and diligence than ever in the future
Rant complete!
Solution: Start a DIY thread for ailments and surgeries and we can help ourselves
Funny true story: While shopping for a new doctor many years ago, I did ask one prospects receptionist what the Doc's grade point average was. She smirked and pointed to his diploma on the wall.
