herpes simplex
"Right before bed I felt the tingle and saw the tiny hint of a cold sore. Not new to this, and knowing I couldn't get prescription meds until the next day, I sent my husband to the store to get Abeva. I applied it that night and in the morning and again mid morning. I went to the doctor in the afternoon to get a prescription medication. Before I got home from the pharmacy I had a HUGE cold sore. I took the meds and continued the Abreva. The cold sore continued to grow in size and is hideous. I stopped the Abreva and am using Petroleum on the lip with the medication. It's slowly getting better now. I'll never use Abreva ever again."
