<s>[INST] I have a total ankle rplmt that has gave me awful swelling and pain since it was done 7 years ago. I also have hep c. I am a nurse but am not working now. I am scheduled to start hep c drugs in 8 days however I had a pus filled pocket on my tar ankle that busted about 5 mo. Ago I have been on keflex 500mg tid but now it has become a hole with white around it and constantly draining pus and liquid. The rx was wrote to take for 10 mo. Does it sound like I could have a staph inf and should I continue with my plan on starting hep c treatmen [/INST] Hi, Thanks for contacting HCM. With any TAR and possible infection, it is recommended to have a physician evaluation to prevent any larger situations. Usually with sores, a culture can be taken to determine the correct antibiotic to treat the area. With drainage and purulence, this can definitely indicate an infection of some kind. It is usually recommeded to take care of any infections in close proximity to a TAR first, then proceed to other treatments.I hope this helps answer your question. Thanks. </s>
