Rash on center of chest

A couple of days ago I noticed a small red area in the center of my chest.  The rash does itch but benedryl cream has helped.  The area is about 2 in. x 2 in. and looks somewhat like fever blisters.  The area feels bumpy and is red.  Should I have this looked at or wait and continue with the Benedryl?

I think you should have it looked at to rule out infection, if possible.  Seborrheic dermatitis commonly affects the chest, but that's scaly rather than blistery.  See a doctor if you can arrange it--perhaps a walk-in clinic to start.  They can refer you on if needed.

Best.
