Foot blisters: If the blisters are grouped and are painful you may have to rule out herpes zoster with superinfection. You may also need to update tetanus vaccination. You definitely need an exam to rule out foreign object/contact dermatitis and other possible differential diagnoses. Consider the history when it started, any barefoot exposure. Rule out pregnancy before treating. Good luck.
