Hi, My husband was diagnosed with stasis ulcers. and they regularly come up, painful scabs. treatment with 2% Mupopirocin would heal these ulcers /scabs quickly before. A week ago these scabs appeared again. This time even with treatment with Mupirocin ointment religiously , the lesions are not improving , the areas around the scabs are red and swollen. Augmetin was given orally, but it seems very little is happening. should we try Levaquin or Keflex instead? Please advise. Thank you
