I have been taking Polysporin for 5 days and have developed a rash on my neck under my chin.  The rash itches  more than anything and does not seem to be red.  This is the only change I can remember making in the last few days.  Could the Polysporin cause it and if so, what can I use instead of this to keep stitches around my knuckles moist?
HIT hank of asking to ChatDoctorLocal antibiotic hardly produces any reaction, and if at all it induces such thing then can only be a local one and not general, your rash is not because of the Polypoid. It may be contact dermatitis, you can try local cream containing steroid it will help a lot. Have nice day.
