10 days keflex for strep b group uti, still symtomatic and lukocytes in urine (bladder pressure/freq urinate/back pain), now on cipro, (ciprofloxacin) what's going on?

Cystitis: You need to see a urologist and be fully evaluated. Sounds as if you may have upper urinary tract infection, in which case evaluation for some anatomic abnormality may be warranted, along with a careful assessment of the antibiotic therapy. Grp b strep should be quite sensitive to penicillin derivatives. Keflex levels may not be sufficient to deal with this. See a urologist.
