Yes I Went For A Bone Biopsy (which Is Fine

yes I went for a bone biopsy (which is fine by the way) about 6 weeks ago.I got an infection and the dr gave me clindamyacin 300mg tid, for 14 days. I am feeling about 25-30% better. She went on vacation and her office will not renew rx and they are too busy to fit me in until the 29th. Obviously if I stop the antibiotics it will blow up. I am going to a walk in clinic tomorrow and was wondering do you think it would be best to do 2 antibiotics such as Clindomyacin and Cipro or Cipro and Rifampin? I am an RN and I do not want to go on IV drugs as I think this can be fixed orally. I am an extremely healthy person
and the clindo IS working but slowly. What do you think?
