6 weeks ago I had foot surgery (modified brostrom procedure to tighten up ligaments near ankle, and a procedure to correct a calcaneonavicular coalition). I have on incision along my ankkle, and another incision on my foot. My cast came off 3 weeks after surgery. 5 weeks after surgery, when I was changing my dressing, I saw some some black stitches from the ankle incision on my gauze pad. I called the doctor's office, and the medical assistant said that that was normal. After that, I noticed drainage for a few days when I changed the dressing. I called doctor's office back, because my foot was feeling hot and I was having a burning pain. They put me on an antibiotic (keflex). And I was told to stop walking and go back to non weight bearing. They told me not to clean the incision. I have only been on antibiotic for 3 days, and it is a 10 day course. In the evenings, especially when I am in bed, I wake up because there is so much pain in my foot, it feels like a deep stabbing pain that is sharp, and sometimes burning. Is this normal of a skin infection from an incision? Could it be a bone infection? Or nerve damage? How patient should I be with this doctor and doctor's office?
