I had cellulitus and had to take both intravenous and oral antibiotics. It initially spread from a swollen ankle up my leg. Everything has healed it except where the initial infection started. It has been over 2 months and I still have it on my ankle. It is no longer red, feverish or hurt anymore but it is stubbornly there on my ankle only. I took 2 dosage of antibiotics for 10 days each. What should I do?
