<s>[INST] I have been having a red, swollen earlobe for over a year. After many diagnosis of eczema, fungal infection and reaction to earrings, all of which was incorrect. Finally, it was swabbed and sent to lab. I was told it was e-coli. I cannot take ciprofloxacin, due to many side effects, so I was told to apply Neosporin for a month for it to clear up. I would like to get your opinion on this matter. [/INST] Hello, Thnx to contact us. I understand your concern. If I am your treating doctor I advice you that neosporin powder is good choice for treatment to local treatment. But if the E. coli is resistant to multiple infection I advice to start with oral antibiotics like cefixime. Maintain the good local hygiene.If you have anything else to ask, kindly contact me.Wish you a very good health at health care magic. Dr. Arun Tank. Infectious Disease. </s>
