It's hard for me to believe that it could be allergies, as she is nearly 6 years old and has never in her life had hotspots or allergy problems of any kind. Also once greys brought up nail clipping I realized it had shown up 1-2 days after I clipped her nails, so I still feel that is the most likely cause, that she scratched her face with a newly clipped nail and made a raw spot, and then made it worse by either scratching it more or rubbing her face on the floor/couch. Would Benadryl help itching from any cause such as the normal itching of a healing wound, or does it just help with allergic type itching?
