It has been 5 1/2 weeks since my operation for AVR and CABG and although my leg incisions have completely healed on the outside I can't say the same for my chest incision. As of this date I still have an open wound along this incision that requires daily care. There is a clear sticky fluid that leaks from the wound very slowly but just enough to keep it from scabbing over and healing . Seems like I am doing the same routine over daily with no improvement in the healing. how long should it take for the chest wound to heal over on the outside.
