Not to worry about her "hole" Luke. Hubby had bypass surgery in one of Houston's premier heart institute and the same thing happened to his incision (on his thigh).
All the doctors (internist, infectious disease) were scratching their heads, hinting he might need to have a second surgery to irrigate the infection.
The brilliant (his website is outstanding!) surgeon opened it up with three deep holes and instructed me how to clean it out every few hours. After 13 days locked in the hospital, he was allowed to finally come home. Doc poked three holes with some sterile scissors! I swabbed it deeply with Betadyne (sp) daily and he recovered just fine.
Keep the faith. You're probably getting sound medical advice.
You have indeed gotten valuable advise here, IMHO.
My HO comes from nursing my mother back from a staph infection in an incision following surgery. The tunneling you describe makes it sound like our situation. In addition to the saline dressings (put on wet, allowed to dry, then changed) and the silvadene, etc., remember
your eyes are the ones to see the wound regularly, so trust yourself.
What I'm saying is, if you feel it's not getting better, make certain someone hears you.
I had a hard time getting anyone to listen. She had months of antibiotic therapy IV.
It sounds as if you've got a good handle on it, Pop.
Prayer of the Order of St. Luke
"Almighty God, who inspired Your servant Luke the Physician to set forth in the Gospel the love and healing power of Your son: Graciously continue in Your Church the love and power to heal, to the praise and glory of Your Name, through Jesus Christ, our Lord.
Amen."
