Thank you for the reply. For all of the surgeries, I took painkillers for about a week or less as they didn't do much for the most part. When you involve bone, the pain is hard to manage. After the first week, the intense pain settled into a lower level of chronic soreness that never went away, but I guess you learn to live with it. I had to insist on something stronger this time and it did work a little better. many Docs seem very reluctant to prescribe stronger narcotics even when warranted.
As of now, following the last surgery I am relieved to say that things are looking up. No signs of infection and while I still have a little soreness, it is in a much different area (not as far up the root) and it is improving. It is still by no means assured but I am hopeful they might be saved. The gums did not close so I've been seeing the surgeon weekly to make sure the area is clean.
The second opinion experience was interesting. In retrospect, it was very alarmist. She had me convinced I had Osteomyelitis and needed to go on long term IV antibiotics immediately. Based on the biopsies that the implanting surgeon did there is no sign of infection at all.
