Cold Sore That Won’t Heal and Go Away: What Experts Say

Cold Sore Won’t Heal and Go WayeMedicineHealth claims that around 80% to 90% of people in the U.S. have been exposed to herpes simplex virus strain HSV-1, the virus that cause cold sore.

The incubation period is about 3 to 6 days, but you may not have any symptoms when you first become infected with the herpes simplex virus, with an outbreak of cold sores may happen some time later.

While cold sores usually clear up without treatment within 7 to 10 days —

According to the University of Wisconsin, the virus HSV-1 may become active again and cause recurrent cold sores:

The virus remains in the body but lies dormant in a bundle of nerves called the trigeminal ganglion and stops causing infection. Cold sores typically recur three to four times a year, although some people may develop more than one cold sore per month.

People often experience tingling, burning, or itching at the site prior to an outbreak. Outbreaks are often spontaneous, without a specific reason or cause, but some common triggers include:

  • overexposure to sunlight
  • stress
  • fatigue
  • illness
  • hormonal changes (premenstrual, pregnancy)
  • surgical procedures or trauma to the site

As such, in case your cold sore on lip is not healing, you are certainly not alone, just as below actual experience and feedback:

‘I’ve had a cold sore, that’s what it looks like at least, for about two years! It won’t go away, and some times it’s really bad… It used to be on one side of my mouth, and now it’s on both. I don’t know what to do to get it to go away. What could I do?’
‘Cold sore at the corner of my lips, won’t go away and keeps splitting open. What can I do to get rid of it? It’s been 3 weeks. I put carmex on it but it doesn’t help. I don’t really know what else to do besides stay away from salts and drink water – which I already do.’
‘Deeply tired of having cold sores.. The doctor put me on a week-long course of Valtrex, 500 mg, 3 times a day. The sores faded after about five days and were blissfully gone by day 7. Unfortunately, they reappeared two days after the course of treatment ended… I started taking acyclovir, left over from a previous bout of cold sore evil, but that didn’t do anything… What should I be doing?’

As per University of Michigan, recurrences of cold sores are normally less severe and individual may notice a burning or tingling sensation 24-48 hours before a cluster of blisters appear.
