I agree with Linda about your seeing an ID specialist, preferably one in the same hospital/network or city as your scoliosis doc. I also have a P. Acnes spinal hardware infection. There are various perspectives on how long to stay on antibiotics. I have IV Picline antibiotics for 6 weeks and am on oral antibiotics now for at least 1 year, but probably for the remainder of my life.
Hope that you find some help for your daughter.
Hang in there and be the best advocate that you can be.
