Hi Dr. Armpit! Upon your advice, I applied the antibiotic cream Neosporin to my armpits for a week and didn't wash them for a few days with no success. Although it did work upon immediate application, the smell returned within 30 minutes to 1 hour. The red rash under my arm did slightly lighten up, but the onion like odor is still present. Could the negative gram bacteria still be dominant? Was applying Neosporin not correct? What did I do wrong? Could it possibly be a yeast infection, or definitely the negative gram bacteria? Which bacterial strain specifically? E Coli? Should I use a stronger antibiotic? I'm still hesitant to put strong stuff under my arms because of the lymph nodes location in such close proximity. Like I said, the Neosporin worked for a little time and then the stench came back. I have also noticed that my lymph node is slightly inflamed. What should I do now that the antibiotic cream hasn't worked? Thank you for your patience and time, Kate
