Suggest treatment for chronic osteomyelitis

Question: Hello, I have spina bifida and lack of sensation from the hips down. Last year, I had an ischial pressure ulcer that was treated and closed at a local wound care center over 2.5 weeks. before I was discharged. Unfortunately, the wound had tunneled and I had a serious infection that included the bone. Long story short, I had multiple surgeries, wound vacs, a colostomy, a blood clot in my leg, 3.5 mos in hospitals and 8 months off from work (I am a research professor at a university). In October, I noticed swelling in my vulvar on the same side as the healed pressure ulcer. I saw my gynecolgist, who referred me to the surgeon to did the colostomy, who referred me to the plastic surgeon who closed the wound, (which was very deep by the time he got to it.) He said not to worry if not symptomatic.
The swelling continued slowly and by May was infected--a drain was inserted and I had IV antibiotics. The swelling lessoned but never totally resolved, and this month i have infection again. Another drain and more meds. Question: Is this likely to be chronic? Can osteomylitis be cured at this point? I am at a good teaching medical center, but am concerned that this was not treated for many months, and now is recurring. Thanks for any general advice you can give.
