No concomitant medications reported by reporter Her doctor doesn't think it's an infection, but she prescribed her antibiotics just in case. She also suggested cortisone cream or ice on it.  When she was leaving the vaccination facility, the HCP put a Band-Aid on her arm, but "not a common one". It was more like a plastic, a half inch wide. After a while, she started to see red under the band aid, so she thought she was having an allergic reaction to it. She took it out and waited.
