bacterial skin infection
"I had burned my arm with a curling iron on Saturday and within a week I had put Neosporin on at least 8 times a day to keep my burn moist and I was also using bandages to help keep it on during work and at bed time.  My arm had become swollen and it itched a lot.  I thought the itching was due to it healing.  I decided to go the doctor due to the swelling.  The swelling was approximately two inches by three inches. Well come to find out I was using too much Neosporin and using it longer than you should. The doctor said I have Cellulitis and I have to take the antibiotic Keflex for 10 days to get rid of it. Always see the doctor first."
