Hello i know that i am HSV-1 Positive however i cant recall ever having a cold sore as big as i have gotten a month ago, or ever for that matter. Here is my story: aug 20th went out did cocaine, on Aug 24th i noticed a bump above my lip 12 hours later i had a huge blister, which i later found out was a cold sore unfortunalty i had popped, it scabbed up by the 29th and on Sept 17th the scab was still going strong. that is when i started using Abreva, the next day miday the scab fell off i did some more cocaine on the 18th as well , possibly because the Abreva made it, on oct 2nd i did coaine as well.it is now Oct 4 and i still have a very red visible mark where it once was. My question: is it normal for a cold sore to take this long to heal? I am not seeking advice for drug use but am merley asking if the use of cocaine could be one of the factors in why my cold sore broke out in the first place and why it is taking so long to heal. thank you.
